Sudden, sharp, or burning pain running down your leg could be sciatica. This happens when the sciatic nerve, which helps control your legs, gets irritated. Often, the pain gets better with rest or therapy. But sometimes it points to a more serious spinal issue that needs urgent medical attention.
If the nerve stays pressed for too long, it can cause lasting nerve damage, muscle weakness, loss of bladder/bowel control, and paralysis. The good news is that early evaluation enables doctors to relieve pressure on the nerve before permanent damage occurs.
Let’s break down what sciatica symptoms need urgent medical attention and when it’s crucial to head to the ER.
Understanding Sciatica
Sciatica isn’t a medical condition itself but rather a symptom of an underlying problem affecting the sciatic nerve, the longest nerve in the body. This nerve runs from your lower back through your hips and buttocks and down each leg.
When something compresses or irritates this nerve, the result is the characteristic radiating pain that defines sciatica. For many sufferers, the pain worsens with prolonged sitting, sudden movements, or coughing and sneezing.
The most common causes include:
- Herniated or slipped disc – A bulging disc can press on the nerve roots.
- Spinal stenosis – Narrowing of the spinal canal can squeeze the sciatic nerve.
- Degenerative disc disease – Age-related wear and tear can irritate the nerve.
- Bone spurs or osteoarthritis – Extra bone growth can cause nerve compression.
- Trauma or injury – Accidents or falls can affect the spine and nerves.
- Pregnancy – Added weight and shifting posture can sometimes trigger sciatica.
Most cases improve with conservative treatment over time. But if symptoms are severe, sudden, or accompanied by other warning signs, don’t ignore it.
6 Red Flags: When Sciatica Pain Becomes an Emergency
While sciatica is usually not a medical emergency, certain symptoms indicate serious complications that require immediate attention. These include:
1. Loss of Bladder or Bowel Control
If you suddenly lose the ability to control your bladder or bowels, or if you experience urinary retention (inability to urinate despite feeling the urge), you need emergency care immediately. This symptom indicates that the nerves controlling these vital functions are severely compressed.
2. Numbness in the “Saddle Area”
Numbness or loss of sensation in the inner thighs, buttocks, or the area that makes contact when sitting is a serious warning sign.
3. Progressive Leg Weakness
Mild weakness is common with sciatica. But if you notice your foot is dragging, you’re unable to stand on your toes or heels, or your leg suddenly gives out, these could indicate severe nerve compression requiring immediate intervention.
4. Pain in Both Legs
Sciatica typically affects only one side of the body. So if you’re experiencing severe pain, numbness, or weakness in both legs at the same time, this could signal a serious spinal problem that needs emergency evaluation.
5. Pain After an Accident or Injury
If your sciatic pain began after a significant injury such as a car accident, serious back injury, or violent impact, you should seek emergency care to rule out fractures, dislocations, or other traumatic injuries to the spine.
6. Fever, Chills, or Unexplained Weight Loss
If your sciatica is accompanied by fever, chills, or unintended weight loss, this could indicate an infection, inflammation, or a tumor affecting the spine or nerves. Spinal infections like epidural abscesses are rare but dangerous.
When to See Your Doctor for Sciatica Pain
Most sciatica doesn’t need an ER visit. But some cases do call for a doctor’s appointment. See your doctor within a few days if:
- Your pain lasts more than a week, even with rest or home care.
- The pain is so strong that it stops you from doing normal activities.
- You get a fever along with back pain.
- You’ve had cancer before and notice new sciatica pain.
- You’re losing weight without trying.
- You take medicine that weakens your immune system.
Managing Sciatica Pain at Home
Many people feel better with simple self-care. The key is to keep moving. Resting for a day or two is fine, but staying in bed too long can worsen pain. Try light activities like short walks or gentle stretching. Other helpful tips include:
- Ice first, heat later: Use ice packs for the first 2–3 days, then switch to heat.
- OTC pain relievers: Ibuprofen or naproxen can ease soreness and swelling.
- Targeted stretches: Loosen up tight hamstrings and hip muscles, which often put pressure on the sciatic nerve.
- Stay active: Once the sharp pain eases, try yoga, swimming, or walking to strengthen your back.
Prevention: Protecting Your Sciatic Nerve
You can lower your risk of sciatica by building healthy habits:
- Sit up straight and use good posture.
- Take breaks to stand and stretch if you keep sitting for long periods.
- Exercise to strengthen your core and back muscles.
- Lift heavy items by bending at your knees, not your waist.
- Keep your weight in a healthy range to ease stress on your spine.
- Use a supportive chair or a standing desk if your job requires sitting all day.
What to Expect in the ER
When you go to the ER for sciatica, medical staff will first assess your neurological function and pain severity. They may ask about when symptoms started, whether you’ve experienced bladder or bowel changes, and if there was any injury. Depending on your condition, tests may include:
- Physical and neurological exam: To check reflexes, strength, and sensation.
- MRI or CT scan: To visualize discs, nerves, and the spine.
- Blood tests: If infection or inflammation is suspected.
- X-rays: To detect fractures or bone issues.
Treatment may involve pain medications, anti-inflammatory drugs, corticosteroid injections, or surgical consultation if severe nerve compression is found.

FAQs
1. Can sciatica pain ever be a sign of a heart attack?
Rarely, heart problems can cause pain that feels like sciatica. If leg pain comes with chest pressure, shortness of breath, or jaw pain, call 911.
2. Is sciatica pain worse at night a reason to go to the ER?
Not usually. But if night pain comes with fever, weight loss, or weakness, see a doctor promptly.
3. Can pregnancy-related sciatica ever require emergency care?
Most pregnancy sciatica isn’t an emergency. Seek immediate care only if severe pain is paired with bleeding, leaking fluid, or contractions.
4. Can sciatica cause permanent damage if I don’t go to the ER?
Regular sciatica rarely causes lasting damage. But untreated cauda equina syndrome can lead to permanent nerve problems, so red flags matter.
5. What vitamin deficiency causes sciatica?
Sciatica isn’t usually caused directly by a vitamin deficiency, but certain deficiencies can contribute to nerve damage that may worsen or mimic sciatica symptoms. The most common is a vitamin B12 deficiency, which is vital for nerve health, low levels can cause nerve pain, tingling, numbness, or weakness.
