Taming the pain of sciatica: For most people, time heals and less is more

Despite being a less common cause of low back pain, sciatica is still something I regularly see as a general internist. Primary care doctors can and should manage sciatica, because for most individuals the body can fix the problem. My job is to help manage the pain while the body does its job. When a person’s symptoms don’t improve, I discuss the role of surgery or an injection to speed things up.

What is sciatica?

Sciatica refers to pain caused by the sciatic nerve that carries messages from the brain down the spinal cord to the legs. The pain of sciatica typically radiates down one side from the lower back into the leg, often below the knee. The most common cause is a bulging (“herniated”) disc in the lower back. Discs are tire-like structures that sit between the bones of the spine. If the outer rim of the disc tears, usually due to routine pressure on the lower back, the jelly-like inner material can come out and pinch or inflame the nearby nerve. Sciatica is most common in people 30 to 50.

How do you know if it is sciatica?

The key to diagnosing sciatica is a thorough history and a focused exam. Unfortunately, many patients expect an x-ray or MRI, and doctors, often facing time constraints, order one even though we know imaging tests don’t really help us treat early sciatica any better. The Sciatica symptoms are often worse with sitting or coughing and may be accompanied by numbness or tingling in the leg. A physical exam can confirm that the sciatic nerve is involved, and I look for weakness or diminished reflexes in the legs that suggest that someone needs early referral to a specialist. (This doesn’t happen often.) With this information, I can make an initial diagnosis and start treatment.

Treating sciatica pain… and managing expectations

Many people think (understandably) that the worse the pain, the more likely something bad is going on. However, this isn’t true for sciatica. The body can reabsorb the disc material that is causing symptoms, even for those with severe pain. So, treatment focuses on controlling pain and keeping people as active as possible. If the pain is excruciating, lying down for short periods can help, but prolonged bed rest does not. So, once the pain diminishes, I tell patients to get up and start walking short distances. Since sitting increases pressure on the discs in the lower back, I recommend avoiding prolonged sitting or driving. Many people try treatments like physical therapy, massage, acupuncture, and chiropractic manipulation, but evidence suggests that while these approaches may help typical low back pain, they are less helpful for sciatica. Over-the-counter pain medicines like ibuprofen and naproxen can help. When they don’t, I may recommend short-term use of stronger, prescription pain medicines.

The good news is that for most (roughly three out of four) people, symptoms improve over a few weeks. Rarely, I’ll find weakness on exam, such as a foot drop, and refer for immediate surgical evaluation. For those not improving after six weeks, surgery is an option. We know surgery can speed up recovery, but by six to 12 months people who have surgery are usually doing about as well as those who decide to just give the body more time to heal on its own. Surgery involves removing the disc material that is affecting the nerve. It is generally a very safe procedure, and while complications are rare, they can happen. What’s more, 5% to 10% of people who have surgery will not be helped by it or may have worse pain afterwards.

Patients often ask about spinal injections — where steroid medicine is injected into the affected area. It is worth considering for those with uncontrolled pain or for those with persistent, bothersome symptoms who want to avoid surgery. Injections can provide short-term relief. Like any procedure, it has uncommon risks including more pain, and it doesn’t seem to decrease the need for future surgery.

Staying patient-focused… and “hurt” doesn’t always mean “harm”

For most patients with sciatica, it’s worth seeing your primary care doctor. Patients who come in are often scared. Typically, it is pain the likes of which they may have never had. They want relief and, rightly, they want it now. That is the appeal of surgery and injections, but I also know that most will get better with time and can avoid even the uncommon risks of these procedures. When I see a patient in my office I can assess and identify the few who need immediate referral to a specialist. But for most, I try to reassure that hurt doesn’t mean harm, and that my treatments are geared to managing pain and keeping them active while the body fixes itself. For those not improving, I will get an MRI prior to referring for surgery or an injection, if the patient decides that speeding up recovery is right for them. For those who feel that they can manage the pain, I can reassure them that they can delay surgery for up to six months without risking long-term problems down the road.

    Dr.Atlas, I had a few questions regarding this article and sciatica. Why is the pain associated with sciatica worsened when coughing? Is it because coughing increases pressure on the discs in the lower back like sitting? Also, I know that this article includes ways of reducing pain and managing symptoms but is it possible for the symptoms of sciatica to completely disappear without external help such as surgery or injections? Lastly, is it possible to have sciatica with chronic back pain as well? Thank you!

      You’re correct – things that increase pressure in the disc space can worsen sciatica. This includes things like bending over, sitting and coughing. Regarding your question about symptoms disappearing without external help, this is a key point of my piece. Yes, for most (over 75%) symptoms improve with time. We believe this is related to inflammatory cells in the body recognizing the disc material that has migrated out of the disc itself as being out of place and working to reabsorb the material. This can take weeks, which is why sciatica typically lasts longer than usual low back pain due to muscle or soft tissue strains. Also, it isn’t clear whether injections help the body resolve the problem. Studies are conflicting on whether injections decrease the need for subsequent surgery. But it is possible that the anti-inflammatory agents used may prevent the body from healing itself as noted. Finally, it is possible to have chronic back pain with sciatica. This includes patients with chronic low back pain who then develop sciatica due to a new disc herniation or those who actually have sciatica for a long period of time. The challenging issue is that surgery appears less effective in those with chronic sciatica. Depending on the study, this refers to symptoms that have lasted more than 6 – 12 months.

    I am surprised you didn’t mention stretching and/or yoga, both of which are effective in managing sciatic pain and symptoms; yoga has a specific stretch, lying on one’s back, that addresses sciatica;

      Thanks for your comment. In a short piece like this, it is hard to cover everything. I do refer to physical therapy that would include stretching. These treatments can help keep one active as the body deals with the disc herniation, but there isn’t much evidence that these treatments, including yoga, decrease pain or affect the overall outcome. Most studies showing the benefit of yoga have been in those with chronic back pain without sciatica.
