When you visit a doctor for sciatic nerve pain, the first appointment typically involves a focused physical exam, a conversation about your symptoms, and a treatment plan that starts conservatively. Most doctors won’t order imaging or recommend anything invasive right away because about 75% of sciatica cases improve significantly within three months, and 90% resolve with non-surgical care. Your doctor’s job is to confirm the sciatic nerve is involved, rule out anything serious, and get your pain under control while your body heals.
The Physical Exam
Your doctor will perform specific maneuvers designed to reproduce your pain in a controlled way. The most common is the straight leg raise: you lie on your back while the doctor slowly lifts your extended leg to about 30 to 60 degrees. If this triggers pain that radiates from your lower back down your leg, it strongly suggests nerve root irritation. A variation of this test involves lowering the leg slightly and flexing the foot upward, which increases tension on the sciatic nerve and can pinpoint the problem more precisely.
If you’re sitting on the exam table, the doctor may try the tripod sign. They’ll straighten one of your legs while you’re seated. A positive result means you instinctively lean back and brace yourself with both arms to relieve the pain, forming a tripod shape. For suspected involvement of the upper lumbar nerve roots, you might lie face down while the doctor bends your knee and lifts the leg. Pain radiating down the front of your thigh points to a different set of nerve roots than classic sciatica.
The doctor will also test your reflexes, muscle strength, and sensation in your legs and feet. These details help identify exactly which nerve root is compressed and whether there’s any neurological damage that needs closer attention.
Why You Probably Won’t Get an MRI Right Away
Most people expect imaging at their first visit, but guidelines from the American College of Radiology recommend against it for uncomplicated sciatica lasting less than six weeks. The reasoning is straightforward: acute sciatica with no red flags is a self-limiting condition that responds to conservative care in most patients, and early MRI findings rarely change the initial treatment plan. Many people without any back pain have disc bulges on MRI, so imaging too early can lead to overtreatment.
Your doctor will typically recommend imaging after six weeks of treatment that hasn’t produced meaningful improvement, or sooner if you have worrying symptoms like progressive weakness, loss of bladder or bowel control, or a history of cancer. When imaging is ordered, MRI of the lumbar spine is the standard choice because it shows soft tissues like discs and nerves in detail. The goal at that point is to identify a specific structural problem that could be targeted with an injection or surgery.
First-Line Medications
Over-the-counter anti-inflammatory drugs like ibuprofen and naproxen are the typical starting point. They reduce inflammation around the compressed nerve root, which is often a major contributor to pain. Your doctor may also prescribe a short course of oral corticosteroids to bring down severe inflammation quickly, though these aren’t meant for long-term use.
If the pain has a burning or electric quality, which is common with nerve irritation, your doctor might add a medication originally designed for seizures or depression. These drugs work by dampening overactive nerve signals and can be particularly helpful for the shooting, tingling component of sciatica that standard painkillers don’t fully address. Opioids are sometimes prescribed for severe acute episodes but are generally avoided beyond a few days because of their side effects and dependence risks.
Physical Therapy
A referral to physical therapy is one of the most common steps a doctor takes. A physical therapist will assess your movement patterns and design a program that typically includes core stabilization exercises, stretching, and a technique called nerve flossing (or nerve gliding). Nerve flossing uses gentle, controlled movements to encourage the sciatic nerve to slide more freely through the surrounding tissues. The goal isn’t to forcefully stretch the nerve but to reduce adhesions and restrictions that develop when the nerve has been compressed or irritated.
One common nerve flossing exercise involves lying on your back, pulling one leg up with a strap or towel while keeping the knee straight, then slowly flexing and pointing the foot to glide the nerve back and forth. A seated version has you straightening one leg at a time while pulling the foot toward you, repeating five to ten times per side. These exercises are combined with broader strengthening work to support your spine and prevent recurrence. Most doctors recommend at least six weeks of consistent physical therapy before considering other interventions.
Epidural Steroid Injections
If your pain persists despite medication and physical therapy, your doctor may recommend an epidural steroid injection. This delivers a concentrated anti-inflammatory medication directly to the area around the irritated nerve root, which can provide more targeted relief than oral medications.
The results are variable. Many people experience meaningful pain relief, but it tends to be temporary, lasting anywhere from a few weeks to several months. Some people get enough relief to participate more fully in physical therapy, which is often the real goal. The injection buys time for healing rather than fixing the underlying problem. Not everyone responds, and the degree of relief varies between patients and even between different injection techniques. Most doctors limit the number of injections to three or four per year.
When Surgery Becomes an Option
Surgery is reserved for a small percentage of sciatica cases. The two main reasons a doctor will recommend it are persistent pain after an adequate course of conservative treatment (at least six weeks of physical therapy, medications, and possibly injections) and progressive neurological problems like worsening leg weakness or loss of sensation.
The most common procedure is a microdiscectomy, where the surgeon removes the portion of a herniated disc that’s pressing on the nerve. It’s a relatively small operation, and most people notice immediate improvement in leg pain afterward. Recovery typically involves a few weeks of limited activity followed by a gradual return to normal movement.
Red Flags That Change the Timeline
In rare cases, sciatica signals a condition called cauda equina syndrome, which requires emergency surgery. Your doctor will ask about specific symptoms at every visit because this condition can develop gradually. The hallmark signs include urinary retention (your bladder fills but you don’t feel the urge to go), loss of bowel or bladder control, numbness in the groin and inner thigh area sometimes called “saddle anesthesia,” and sudden weakness in both legs. If you develop any of these symptoms between appointments, go to an emergency room immediately. Cauda equina syndrome can cause permanent damage if not treated within hours.
What Recovery Typically Looks Like
Most sciatica episodes follow a predictable arc. Pain is often worst in the first two weeks, then gradually improves over the course of one to three months. About 75% of people see their pain completely or partially resolve within that three-month window. The leg pain usually fades before the back pain does, which is actually a good sign because it means the nerve is decompressing.
A significant minority, up to 30%, still have some degree of pain after a year. For these cases, doctors may cycle through additional rounds of therapy, injections, or ultimately surgery. But for most people, the initial conservative approach your doctor starts at that first visit is all that’s needed.
