Lower back pain that spreads into the buttock or leg can significantly affect sitting, walking, working, sleeping, and other everyday activities. One possible cause is a lumbar disc herniation, commonly referred to by many patients in Bangladesh as PLID (Prolapsed Lumbar Intervertebral Disc).
PLID does not affect everyone in the same way. Some people experience mainly lower back pain, while others develop sciatica, numbness, tingling, or weakness because a nearby nerve root becomes irritated or compressed. Importantly, finding a disc bulge or herniation on an MRI does not automatically mean that it is responsible for every symptom.
At Asia Digital Physiotherapy Orthopedic Rehabilitation Center (ADPORC), Jatrabari, Dhaka, PLID rehabilitation is planned according to the patient's symptoms, neurological findings, movement limitations, daily activities, and functional goals. For many patients without serious neurological deficits, conservative management including education, appropriate activity modification, and individualized physiotherapy can form an important part of recovery.
What Is PLID?
PLID stands for Prolapsed Lumbar Intervertebral Disc. In current medical literature, the condition is commonly described as lumbar disc herniation (LDH).
The lumbar spine consists of five vertebrae in the lower back. Between the vertebrae are intervertebral discs that help absorb load and allow the spine to move. Each disc contains a softer central portion surrounded by a ber outer layer.
A lumbar disc herniation occurs when disc material extends beyond its normal boundary. Depending on its shape and extent, imaging reports may use terms such as protrusion, extrusion, or sequestration.
A disc herniation can sometimes irritate or compress a nearby nerve root. When this happens, symptoms may extend beyond the lower back into the buttock, thigh, leg, or foot.
However, not every lumbar disc herniation causes symptoms. MRI findings must therefore be interpreted together with the patient's clinical history and physical examination.
PLID, PIVD, Disc Bulge and Herniated Disc: Are They the Same?
These terms are often used interchangeably by patients, but they do not always mean exactly the same thing.
- PLID: Usually refers specifically to a prolapsed or herniated disc in the lumbar spine.
- PIVD: Prolapsed Intervertebral Disc is a broader term that may refer to disc prolapse at different levels of the spine.
- Disc Bulge: Describes a broader extension of the disc beyond its usual boundary. A disc bulge is not necessarily the same as a focal disc herniation.
- Lumbar Disc Herniation: The commonly used medical term for localized displacement of lumbar disc material.
- Slipped Disc: A common non-medical expression. The entire disc does not literally “slip” out of place.
Understanding this distinction is important because an imaging finding alone should not determine treatment. Symptoms, neurological findings, function, and clinical assessment should also be considered.
Where Does PLID Commonly Occur?
Lumbar disc herniation most commonly affects the lower segments of the lumbar spine, particularly:
- L4-L5
- L5-S1
These levels experience substantial mechanical loading and movement during daily activities.
The symptoms can differ depending on which nerve root is affected. For example, some patients may experience pain or altered sensation along different areas of the leg or foot, while others may develop weakness in particular muscle groups.
The location of pain alone is not enough to identify the affected disc level. Muscle strength, sensation, reflexes, neurological testing, and imaging when clinically indicated help build a more complete picture.
Common Symptoms of PLID
Symptoms can vary considerably from person to person. Common presentations include:
- Lower Back Pain: Pain may be aching, sharp, or activity-related.
- Sciatica or Radiating Leg Pain: Pain may travel from the lower back or buttock into the thigh, calf, or foot.
- Numbness or Tingling: Altered sensation may occur along the distribution of an irritated nerve root.
- Leg or Foot Weakness: Nerve involvement can affect the strength of certain muscles.
- Pain With Coughing or Sneezing: Increased spinal pressure may aggravate radicular symptoms in some patients.
- Difficulty Sitting for Long Periods: Some patients find prolonged sitting particularly uncomfortable.
- Reduced Walking or Functional Tolerance: Pain or neurological symptoms may interfere with work, household activities, exercise, or mobility.
Some people with lumbar disc herniation have significant leg symptoms with relatively little back pain.
PLID and Sciatica: What Is the Connection?
Sciatica is a symptom pattern, not a separate diagnosis.
It usually describes pain that follows the distribution of the sciatic nerve into the buttock and leg. A lumbar disc herniation is one possible cause of sciatica because displaced disc material or local inflammation may irritate a spinal nerve root.
However, not every person with PLID develops sciatica, and not every case of leg pain or sciatica is caused by PLID.
Other conditions may produce similar symptoms, which is why a clinical assessment is important before deciding that a lumbar disc is the source of the problem.
What Causes PLID?
Lumbar disc herniation does not usually result from one single factor. Disc structure changes over time, while genetic, lifestyle, occupational, and mechanical factors can influence the likelihood of developing symptoms.
Factors associated with lumbar disc herniation may include:
- Age-Related Disc Changes: Intervertebral discs gradually change in hydration and structure with age.
- Repeated Heavy Physical Loading: Frequent manual handling, lifting, bending, or physically demanding work may increase cumulative lumbar loading.
- Sudden High Load or Injury: Symptoms can sometimes begin after lifting, twisting, or another forceful movement.
- Smoking: Smoking is associated with lumbar disc degeneration and symptomatic lumbar disc herniation.
- Higher Body Weight: Higher BMI is associated with increased risk in some populations and may also affect overall physical loading.
- Genetic Factors: Individual susceptibility to disc degeneration and herniation can partly be influenced by genetics.
It is too simplistic to say that PLID occurs only because someone sat with “bad posture” or lifted an object incorrectly. These activities may aggravate symptoms in some people, but disc herniation is usually influenced by multiple factors.
How Is PLID Diagnosed?
Diagnosis should combine the patient's history with a structured physical and neurological examination.
A physiotherapy or medical assessment may include:
- Pain History: Location, duration, onset, severity, aggravating activities, and whether pain travels into the leg.
- Movement Assessment: How lumbar and lower-limb movements affect symptoms.
- Muscle Strength Testing: Checking for weakness that may suggest nerve-root involvement.
- Sensation Testing: Looking for numbness or altered sensation along specific areas of the leg or foot.
- Reflex Examination: When clinically appropriate.
- Straight Leg Raise or Related Tests: These may help assess nerve-root irritation in combination with other findings.
- Functional Assessment: Walking, sitting tolerance, work tasks, lifting, and other activities relevant to the patient.
No single physical test should be used alone to confirm PLID.
Do All PLID Patients Need an MRI?
No.
MRI is useful for visualizing intervertebral discs, nerve roots, and other spinal structures, but imaging is not routinely required for every episode of lower back pain or sciatica.
MRI may become more relevant when:
- symptoms persist and imaging is likely to influence further management;
- significant or progressive neurological weakness is present;
- serious spinal pathology is suspected;
- surgery or another specialist intervention is being considered.
MRI findings also need clinical correlation because disc bulges and protrusions can be found in people who have no back or leg symptoms.
Therefore, treatment should not be based on an MRI report alone.
Can PLID Improve Without Surgery?
Yes. Many patients with symptomatic lumbar disc herniation can initially be managed without surgery when there is no cauda equina syndrome, progressive significant motor weakness, or another serious neurological problem requiring urgent medical management.
Conservative treatment may include:
- patient education;
- appropriate continuation or modification of daily activity;
- physiotherapy and exercise rehabilitation;
- symptom management;
- gradual return to normal work and physical activity;
- medical management when indicated and prescribed by an appropriate clinician.
The body can also reduce the size of some herniated disc material over time through a process known as spontaneous resorption. This does not happen in every case, and recovery cannot be predicted from MRI appearance alone.
The goal of rehabilitation is therefore not simply to “push the disc back into place.” It is to improve symptoms, restore movement and strength, increase functional capacity, and help the patient safely return to everyday activities.
How Physiotherapy Helps in PLID
Physiotherapy for PLID should be based on assessment rather than a fixed treatment protocol.
At ADPORC, rehabilitation may focus on the following areas depending on the patient's presentation:
Patient Education and Symptom Management
Understanding the condition can reduce unnecessary fear and help patients make better decisions about movement, activity, work, and rehabilitation.
Education may include advice about:
- staying appropriately active;
- modifying temporarily aggravating activities;
- changing positions when required;
- understanding nerve-related symptoms;
- gradually returning to normal activity.
Individualized Exercise Therapy
Exercise is selected according to the patient's symptoms, movement response, stage of recovery, strength, and functional requirements.
Treatment may involve:
- lumbar movement exercises;
- trunk and core muscle rehabilitation;
- hip and lower-limb strengthening;
- mobility exercises;
- endurance training;
- progressive functional exercise.
There is no single “best PLID exercise” that is suitable for every patient.
Gradual Restoration of Movement
Patients who have avoided movement because of pain may gradually develop stiffness, weakness, and reduced physical confidence.
Physiotherapy helps restore comfortable movement progressively rather than encouraging prolonged rest.
Neural Mobility When Appropriate
Some patients with radiating leg symptoms may benefit from carefully selected neural mobility techniques. These should be prescribed according to irritability and neurological findings rather than performed aggressively.
Manual Therapy When Clinically Appropriate
Manual therapy or mobilization may sometimes be used to assist short-term symptom management or movement as part of a broader rehabilitation program.
Manual therapy does not physically push a herniated disc back into place and should not replace active exercise and rehabilitation.
Functional and Work Rehabilitation
As symptoms improve, rehabilitation should progress toward the activities that matter to the patient.
This may include:
- prolonged sitting tolerance;
- walking;
- bending;
- lifting;
- carrying;
- stair use;
- occupational activities;
- exercise or sport.
The aim is not simply to reduce pain but to restore meaningful function.
Exercises for PLID: Why They Must Be Individualized
People often search online for the “best exercise for PLID.” The difficulty is that the same movement can help one patient but aggravate another.
Exercise selection depends on factors such as:
- whether symptoms remain in the back or radiate into the leg;
- which movements improve or worsen symptoms;
- neurological findings;
- current pain irritability;
- strength and mobility;
- stage of recovery.
Examples of exercise categories that may be introduced after assessment include:
- Gentle Walking: To maintain general activity and gradually improve tolerance.
- Lumbar Movement Exercises: Selected according to the patient's individual response.
- Trunk Stabilization Exercises: Progressed from basic control to more demanding functional tasks.
- Hip and Lower-Limb Strengthening: To improve overall movement capacity.
- Functional Training: Gradual practice of sitting, bending, lifting, and work-related tasks.
Stop an exercise and seek assessment if it causes significant new weakness, rapidly increasing numbness, marked worsening of leg symptoms, or other concerning neurological changes.
Home Care and Activity Advice
During recovery, the goal is usually to remain appropriately active rather than staying in bed for long periods.
General advice may include:
- Change Position Regularly: If prolonged sitting or standing aggravates symptoms, vary your position throughout the day.
- Avoid Prolonged Bed Rest: Extended inactivity may contribute to weakness and reduced activity tolerance.
- Walk According to Tolerance: Short, comfortable walks can often be progressed gradually.
- Temporarily Modify Aggravating Loads: Reduce or adapt activities that clearly worsen symptoms, then rebuild tolerance as recovery progresses.
- Use a Comfortable Sleeping Position: There is no single mattress firmness or sleeping position that is best for every PLID patient.
- Follow an Individualized Exercise Program: Avoid copying exercises solely from social media or videos without considering your symptom pattern.
- Return to Activities Gradually: Improvement does not mean immediately returning to maximal lifting or physically demanding activity.
When Does PLID Need Surgery?
An MRI diagnosis of PLID does not automatically mean surgery is required.
A specialist surgical opinion may be considered when:
- significant or progressive muscle weakness is present;
- severe sciatica continues to substantially limit function despite appropriate non-surgical treatment;
- imaging findings match the patient's neurological symptoms and surgery is being considered;
- cauda equina syndrome or another neurological emergency is suspected.
The decision depends on symptoms, neurological status, functional limitations, imaging findings, treatment response, and specialist assessment.
Physiotherapy should therefore not be described as a method that guarantees surgery can be avoided. Rather, conservative rehabilitation is commonly the first-line approach for appropriate patients who do not have serious neurological deficits.
Red Flags: When PLID Requires Urgent Medical Assessment
Most cases of lumbar disc herniation are not emergencies. However, certain neurological symptoms require urgent medical evaluation.
Seek urgent medical care if you develop:
- new difficulty controlling urination or bowel function;
- numbness around the inner thighs, genitals, or saddle area;
- rapidly progressive or significant weakness in one or both legs;
- severe neurological symptoms affecting walking or lower-limb function.
These symptoms may indicate serious nerve compression such as cauda equina syndrome and should not be managed as routine back pain.
Can PLID Come Back?
Symptoms can recur, even after a successful recovery. No exercise or treatment can guarantee that lumbar disc problems will never return.
Long-term rehabilitation can focus on improving factors that are within the patient's control, including:
- regular physical activity;
- trunk and lower-limb strength;
- gradual exposure to lifting and occupational loads;
- maintaining a healthy body weight where appropriate;
- avoiding smoking;
- maintaining general cardiovascular fitness;
- continuing exercise after symptoms settle.
The goal is to build physical capacity and confidence rather than permanently avoiding normal spinal movement.
When to See a Physiotherapist for PLID
A physiotherapy assessment may be appropriate when:
- lower back pain or leg pain continues to interfere with daily activities;
- you experience recurring sciatica or disc-related symptoms;
- sitting, walking, bending, or working has become difficult;
- you are unsure which exercises or activities are appropriate;
- symptoms have improved but you need guidance returning to work, exercise, or normal activity.
If significant weakness, bladder or bowel changes, saddle numbness, or another red flag is present, urgent medical assessment should take priority over routine physiotherapy.

Conclusion
PLID, or lumbar disc herniation, can cause lower back pain, sciatica, numbness, tingling, weakness, and limitations in everyday activities. However, an MRI finding alone does not determine how severe the condition is or whether surgery is required.
For many patients without serious neurological deficits, conservative management and individualized physiotherapy can support recovery. Rehabilitation should focus on education, appropriate activity, progressive exercise, strength, movement, and functional restoration rather than relying on passive treatment alone.
Most importantly, treatment should match the individual patient's symptoms and neurological findings. Early identification of progressive weakness or cauda equina symptoms is essential so that urgent medical care is not delayed.
