Most sciatica resolves without surgery. About 90% of acute sciatica episodes improve with conservative treatment alone, typically within a few weeks to a few months. The key is managing pain in the short term while addressing the underlying cause, usually a herniated disc pressing on the sciatic nerve in your lower back. Here’s what actually works, in the order you should try it.
What’s Causing Your Pain
Sciatica isn’t a diagnosis on its own. It’s a symptom of something compressing or irritating the sciatic nerve, which runs from your lower spine down through each leg. The most common culprit is a lumbar disc herniation, where the soft cushion between two vertebrae bulges or ruptures and presses against a nerve root. Less frequently, the cause is spinal stenosis (a narrowing of the spinal canal) or a bone spur. The pain typically travels from the lower back or buttock down one leg, and it can range from a dull ache to a sharp, burning sensation or even electric-shock-like jolts.
Understanding the cause matters because it shapes treatment. A herniated disc often heals as the body gradually reabsorbs the protruding material. Stenosis tends to be more chronic and positional. In both cases, the goal of early treatment is the same: reduce inflammation, take pressure off the nerve, and restore movement.
Ice First, Then Heat
For the first 48 to 72 hours of a flare-up, ice is your best tool. Cold reduces nerve pain signaling and helps control inflammation around the compressed nerve root. Lie down and apply an ice pack to your lower back for 20 to 30 minutes at a time, two to three times a day. Always wrap the ice pack in a cloth to protect your skin.
Once the worst of the acute pain has subsided (usually after that 72-hour window), switch to heat. A heating pad on your lower back for 20 to 30 minutes, two to three times daily, relaxes the surrounding muscles and eases stiffness. Some people find alternating between the two helpful after the initial acute phase. Neither ice nor heat fixes the underlying problem, but they make the early days significantly more bearable.
Keep Moving (Carefully)
Bed rest feels instinctive, but prolonged inactivity makes sciatica worse. Staying as active as you can, even with gentle walking, helps reduce inflammation and prevents the muscles supporting your spine from weakening. The goal isn’t to push through sharp pain. It’s to avoid staying completely still for days at a time.
Specific exercises can speed recovery. Nerve gliding (sometimes called nerve flossing) is a technique that gently mobilizes the sciatic nerve, encouraging healthy blood flow and reducing spots where the nerve may be stuck or compressed. A simple version: lie on your back, bring one knee toward your chest, then slowly straighten that leg while pulling your foot back toward your head. Lower it, relax, and repeat 5 to 10 times on each side. For a deeper stretch, use a towel or strap looped around your foot to raise the straightened leg until you feel a stretch in the back of your thigh, then gently flex and point the foot 10 to 20 times.
Core strengthening is equally important. Your abdominal and back muscles act as a natural brace for your spine. Exercises that engage your core, like drawing your belly button toward your spine during bridges or planks, reduce the mechanical load on the discs and nerve roots. Physical therapists often build programs around these movements because they address the root cause rather than just the symptoms. If your job or daily routine involves heavy lifting, bending, or prolonged sitting, building enough strength and range of motion in your hips, knees, and core is what keeps sciatica from coming back.
Over-the-Counter Pain Relief
Anti-inflammatory medications like ibuprofen or naproxen can help take the edge off during a flare. They work by reducing the inflammation around the nerve root, which is a major driver of the pain. These are most useful in the first few weeks of an episode.
Oral steroids are sometimes prescribed for more intense pain, but the evidence behind them is underwhelming. A large clinical trial at Kaiser Permanente followed 269 adults with acute sciatica confirmed by MRI. Those who took a 15-day course of oral prednisone showed modest improvement in function compared to placebo, but there was no statistically significant difference in pain relief at either 3 weeks or 52 weeks. The steroids also didn’t reduce the likelihood of eventually needing surgery. In short, they may help you move a bit better in the short term, but they won’t meaningfully change your pain or your long-term outcome.
Epidural Steroid Injections
If oral medications and physical therapy aren’t providing enough relief after several weeks, an epidural steroid injection is the next step many doctors consider. This delivers anti-inflammatory medication directly to the area around the compressed nerve root, which is far more targeted than an oral pill.
The results vary. Many people experience meaningful pain relief lasting three to six months, and some get up to 12 months of improvement. The injection typically starts working within two to seven days. Others get little to no benefit. Injections are generally limited to a few per year, and they work best as a bridge, buying you time to continue physical therapy and let the underlying problem heal. They can also reduce the need for surgery, though there’s no guaranteed percentage of people who avoid the operating room because of them.
When Surgery Becomes the Right Option
Surgery is reserved for two situations: emergencies and cases where conservative treatment has genuinely failed. The standard recommendation is at least six weeks of physical therapy and other non-surgical care before considering an operation, since most people improve in that window.
The most common procedure is a microdiscectomy, where a surgeon removes the portion of the herniated disc that’s pressing on the nerve. It’s a relatively small operation with a good track record for relieving leg pain. For stenosis, a laminectomy (removing part of the bone to widen the spinal canal) may be recommended instead. Progressive neurological deficits, like increasing weakness in your leg or foot drop, can also move up the surgical timeline even before six weeks have passed.
Red Flags That Need Emergency Attention
A rare but serious complication of severe disc herniation is cauda equina syndrome, where the bundle of nerve roots at the base of the spinal cord becomes compressed. This is a surgical emergency. If it’s caught before full incontinence develops, surgery can often prevent permanent damage. Left untreated, it can cause lasting bladder and bowel incontinence, loss of sexual function, and even leg paralysis.
Watch for these specific warning signs during any sciatica episode:
- Numbness around the anus or genitals, sometimes described as a “numb bum” when wiping
- Changes in bladder function, including reduced awareness of a full bladder, loss of the urge to urinate, inability to stop your stream mid-flow, or a progressively weakening stream with dribbling
- Numbness or weakness developing in both legs rather than just one
Any of these symptoms alongside sciatica warrants an immediate trip to the emergency room, not a scheduled appointment.
Preventing Recurrence
Treating sciatica and preventing it look very similar. The people who recover and stay pain-free are generally those who maintain core strength, keep their hips and legs flexible, and make sure their body can handle their daily demands. If you sit for long stretches at work, regular movement breaks and a supportive chair matter. If your job is physically demanding, building strength that matches the load you carry every day is what protects your spine. Sciatica has a tendency to come back, but a consistent routine of core work, nerve gliding, and hip mobility exercises significantly lowers that risk.
