Sciatica Often Leaves On Its Own


DEAR DR. DONOHUE: I have had sciatica for two and a half months. Even though I am better than I was at first, I am taking forever to fully recover. I have had chiropractic treatments and physiotherapy.

My doctor tells me it will go away on its own. Books that I have read say that most recover in six weeks. It’s going on three months for me.

I also had vasculitis (Henoch-Schonlein purpura). I haven’t experienced any symptoms for a couple of years. I have been feeling nauseated and have had loose BMs and the odd stomachache. A red spot appeared on my leg a few days ago. Do you think the vasculitis is playing a role in my delay in recovery? — J.B.

ANSWER: I’ll describe the typical pain of sciatica, and you see if the description fits your pain. The sciatic nerve is the body’s largest and longest nerve. It travels from the lower back, down the leg to the ankle or foot. Pressure on the nerve from a protruding back disk, a bone spur or anything that compresses the nerve brings on sharp or burning pain running down the side and back of the leg to the foot.

Pulling the knees to the chest and holding that position for 20 seconds produces sciatica pain.

The pain of sciatica often lessens and disappears in one or two months.

The X-ray report you included doesn’t rule in or rule out sciatica. If the pain persists, an MRI or CT scan provides additional information. You are improving, so I think eventually you should be pain-free.

Vasculitis is an inflammation of blood vessels, and Henoch-Schonlein (HE-knock SURN-line) purpura is one kind of vasculitis. Children get this illness more than adults do. Red blotches that turn into bruises (purpura) pop up on the buttocks and legs. Joint pain, abdominal pain, nausea, vomiting and diarrhea (or constipation) also arise. In the first year after recovery, relapses are common.

If your current stomach troubles worsen or you see more red blotches, get back to the doctor who took care of you before. I don’t believe that HS, if it is returning, is interfering with your recovery from sciatica.

DEAR DR. DONOHUE: As someone preparing for a liver biopsy, please discuss the procedure, recovery and possible side effects. — R.J.

ANSWER: Doctors perform a liver biopsy with a needle attached to a suction device that can capture a thin piece of the organ for microscopic examination. The needle is inserted through the skin over the liver. First the doctor cleans the skin with an antiseptic and often numbs it. The procedure takes less than a minute. You return home shortly thereafter.

Side effects are rare. Bleeding is possible. So is infection. Neither happens frequently.

You don’t have to prepare yourself in any special way.
