Sciatic nerve pain due to L5-S1 disc protrusion

Nadia El ibrahimi

Hello Doctor, I am suffering from lower back pain radiating to my right leg, sometimes reaching the knee and lower leg. The pain feels like burning and electric shocks, worsening with movement and walking, and improves with rest. A lumbar CT scan (TDM) shows a disc protrusion at L5-S1 on the right side. The pain started during pregnancy with twins and now limits my ability to walk and perform daily activities. I would like your advice regarding treatment options, medications, pain relief, and when it is safe to start exercises. Should I consider further tests such as MRI? Thank you very much.

Doctors' responses

Hello Nadia Thank you for sharing your detailed history. Based on your symptoms—lower back pain radiating to the right leg, burning/electric shock sensations, and a CT scan showing an L5-S1 disc protrusion—your pain is most likely due to nerve compression from the disc protrusion (sciatica).

Here’s a structured approach to your questions:


1. Treatment Options Non-surgical treatments are usually the first step: - Physical Therapy: A structured program focusing on core stabilization and gentle stretching can help reduce pain and improve mobility. A physiotherapist can tailor exercises to your stage of recovery and comfort level. - Pain Management: Over-the-counter pain relievers (like NSAIDs) and topical treatments can provide relief. Myofascial release or massage may also help with muscle tension. - Injection Therapies: If pain is severe or not improving, options like epidural steroid injections or platelet-rich plasma (PRP) therapy can reduce inflammation and promote healing. - Lifestyle Adjustments: Maintain a healthy weight, practice good posture, and avoid heavy lifting or prolonged sitting/standing.

Surgery is considered only if: - There is severe or progressive weakness, loss of bladder/bowel control, or if pain is disabling and not improving after several weeks of conservative treatment.


2. Medications & Pain Relief - NSAIDs (e.g., ibuprofen, diclofenac): For pain and inflammation (use only after consulting your doctor, especially if you have any other health conditions). - Topical pain relief gels: Can be applied to the lower back. - Muscle relaxants: Sometimes prescribed for muscle spasms. - Neuropathic pain medications: (e.g., pregabalin, gabapentin) may be considered if pain is nerve-related, but only under medical supervision.


3. When to Start Exercises - Start gentle stretching and core exercises as soon as pain allows, ideally under the guidance of a physiotherapist. Avoid exercises that worsen your pain. - Walking is generally safe and beneficial, but stop if pain increases.


4. Further Tests (MRI?) - MRI is recommended if symptoms persist, worsen, or if there are signs of nerve damage (increasing weakness, numbness, or loss of bladder/bowel control). MRI provides a more detailed view of nerves and soft tissues than CT, and is especially useful for planning further treatment.


Bottom line:
Most people improve with non-surgical treatments. MRI is helpful if pain is not improving or if there are signs of nerve damage. Start gentle exercises as soon as pain allows, and always consult your doctor before starting new medications or therapies.

Thank you and get well soon

Your symptoms and CT finding are consistent with right-sided sciatica from an L5–S1 disc protrusion, which commonly causes burning/electric pain down the leg and often worsens after pregnancy due to spinal strain. An MRI lumbar spine is useful (and preferred over CT) to better assess nerve compression and guide treatment; most patients improve with medications, activity modification, and guided physiotherapy, while injections or surgery are considered only if pain or weakness persists. Specialist consultation: see a spine orthopedic surgeon or neurosurgeon to review imaging, optimize pain control, and advise when to safely start exercises (usually after pain is controlled).

A disc protrusion at L5-S1 compressing or irritating the sciatic nerve could indeed explain the burning, electric shock-like pain you’re experiencing. This is a common site for disc issues that can result in sciatica, and your symptoms are quite typical. Initial management includes conservative treatment such as NSAIDs like ibuprofen or naproxen to help reduce inflammation and pain, but do check with your doctor first, especially given it’s postpartum. Using hot/cold packs, alternating between them might provide some relief — 15 to 20 minutes per session, a few times a day. Physical therapy is often beneficial, although timing is key; once the acute pain is under control, you can start gentle stretching and strengthening exercises under guidance. But be cautious with any activity that increases symptoms. Given your significant symptoms, an MRI could provide more detail on the disc problem compared to a CT scan, particularly soft tissues and nerve involvements, and might be advisable if symptoms persist or worsen. In some cases, nerve root injections or even surgery may be considered if conservative options don’t help enough after several weeks. Observing for red flags like bladder/bowel changes or significant weakness is crucial, as these would need immediate attention. Rest is crucial, but prolonged bed rest is not recommended; try to return to gentle activity as soon as suitable. Engage your doctor to build a comprehensive plan that takes your health history and current situation into account. Do not hesitate to seek more specialized care if pain continues to affect daily functioning.

Your symptoms and CT scan findings are consistent with right-sided L5–S1 disc protrusion causing nerve root irritation (sciatica). The burning, electric-shock–like pain radiating down the leg and worsening with movement strongly supports nerve compression rather than simple muscle pain. Pregnancy, especially twin pregnancy, likely contributed by increasing spinal load and disc stress.

At your age, this condition is usually managed conservatively first, with good outcomes in most patients.

Hello Nadia, thank you for sharing your concern. Firstly I want to clarify that your situation is painful and disabling but not usually dangerous unless some danger signs are present.

Visit a doctor urgently if: Progressive leg weakness, Numbness in groin / saddle area, Loss of bladder or bowel control, Severe night pain not relieved by rest.

You should get an MRI done. Get done MRI Lumbosacral spine (non-contrast).

Regarding medications - It would be better for you if you consult an Orthopedic doctor and take a prescription from him/her. They will do so after examining you properly and cater the medicines according to your needs. Don’t take chat prescriptions, it’ll do more harm than benefit. Better take a one to one consultation with an Orthopedic doctor.

Till then you can safely take- - Tab. Methylcobalamin 1500mcg + Pregabalin 75mg at night × 7 days. - Tab. Paracetamol 650mg when pain appears. - Take this prescription for only 7 days. Proper prescription should be given by an Orthopedic doctor. - Avoid self-medication—doses must be adjusted individually.

Activity modification- Avoid: Bending forward, Lifting weight, Sitting on the floor, Long sitting without back support. Do: Sleep on side with pillow between knees, Firm mattress, Short walks (as tolerated). Complete bed rest is NOT advised

When can you start exercises?- NOT during acute severe pain. Start physiotherapy when: Pain intensity reduces, You can walk short distances without sharp pain. Avoid: Forward bending exercises, Yoga poses involving flexion/twisting, Unsupvised YouTube exercises initially.

80–90% improve without surgery. Disc protrusions often shrink over time. With rehab, you can return to normal activity.

Feel free to reach out again.

Regards, Dr. Nirav Jain MBBS, D.Fam.Medicine

Hello

What’s happening: The L5–S1 disc is pressing on the nerve → causes burning/electric pain down the leg (classic sciatica). Pregnancy can trigger or worsen this due to strain and posture changes.

ANSWERS TO YOUR QUESTIONS

1. Treatment options First line: medicines + physiotherapy + rest Most cases improve without surgery

2. Medications Pain relief: Paracetamol ± NSAIDs Nerve pain: Gabapentin / Pregabalin Muscle relaxant: short-term only (Doctor supervision needed)

3. Pain relief measures Avoid bending, lifting, long sitting Use firm mattress Hot fomentation for back Gentle walking as tolerated

4. When to start exercises After acute pain reduces (usually 1–2 weeks) Start with gentle core & back exercises under physiotherapist guidance

5. Need MRI? Yes, MRI lumbar spine is recommended Especially since pain is persistent and affecting walking MRI is better than CT for discs and nerves

6. Surgery needed? Not now Only if pain lasts >6–8 weeks despite treatment or if weakness develops

Most patients recover well with conservative care.

I trust its clear and helpful Thank you! Take care
