Nerves and Muscles

Will multiple sclerosis affect my pregnancy?

DEAR DOCTOR K: I have multiple sclerosis. My husband and I would like to have a baby. What do I need to know before I get pregnant?

DEAR READER: Multiple sclerosis (MS) is a disease that affects communication between nerve cells in the brain and spinal cord and the rest of the body. This results in symptoms that may include fatigue, weakness, pain and trouble with movement. In the most common form of the disease, sudden worsening of symptoms (flare-ups or relapses) alternate with symptom-free periods (remissions)

What is fibromyalgia?

DEAR DOCTOR K: My sister was just diagnosed with fibromyalgia. Can you tell me more about this condition?

DEAR READER: Fibromyalgia is a somewhat controversial condition, although less so than it was 20 years ago. It causes pain, aches and stiffness in muscles and joints throughout the body. Patients also feel unusually tired. The results of common blood tests, X-rays and other tests are usually normal for people with fibromyalgia, but depression and anxiety are also more common. Some doctors believe that the symptoms of fibromyalgia are explained by these psychological conditions.

What are treatments for chronic neuropathic pain?

DEAR DOCTOR K: I suffer from what my doctor calls "chronic neuropathic pain." What are my treatment options?

DEAR READER: There are two main types of pain. Nociceptive pain results from an injury to tissues outside your nervous system. Burns, sprains and broken bones are all examples of nociceptive pain. Tiny nerve fibers are always present in tissues. When the tissue gets injured, the nerve fibers detect it. The signal they send the brain is nociceptive pain. The signal says to the brain: "Do something to avoid further injury!"

Is it safe for me to ride a stationary bike if I have sciatica?

DEAR DOCTOR K: I have sciatica. Is it safe for me to ride a stationary bike for exercise?

DEAR READER: Sciatica is persistent pain felt along the sciatic nerve. This nerve runs from the lower back, down through the buttock and into the lower leg. Pain results when this nerve is compressed or injured. It most commonly results from inflammation, bone chips caused by arthritis, or a herniated ("slipped") disk in the lower spine.

I strained my hip flexor — how can I relieve the pain?

DEAR DOCTOR K: I've strained a muscle where my hip meets my pelvis. What can I do to relieve the discomfort?

DEAR READER: It sounds like you've strained your hip flexor. That's a group of muscles that runs from your lower back to the front of your thigh. These muscles help flex your hip when you lift your leg to the front. A hip flexor strain can lead to pain where your thigh meets your pelvis, as well as pain or pinching when you pull your knee to your chest or when you climb stairs.

What is a “sliding hernia”?

DEAR DOCTOR K: My mother was recently diagnosed with a "sliding hernia." What is this?

DEAR READER: A "sliding hernia" is a type of hiatal hernia. OK, so what's a hiatal hernia? A hernia occurs when part of an organ juts through an opening into an area where it shouldn't. The stomach is an organ that is supposed to stay in the abdomen, for example. The abdomen is separated from the chest by a flat, dish-like plate of muscle called the diaphragm.

What is Bell’s palsy?

´╗┐DEAR DOCTOR K: I went to my doctor with some alarming symptoms and he diagnosed me with Bell's palsy. I don't know anything about this condition.

DEAR READER: Bell's palsy, named after the person who first reported it in the medical journals, Charles Bell, is a weakness of the muscles on one side of the face. All muscles in your body take their orders from nerves leading to them. When you think of muscles, you probably think of the big, bulky muscles in your arms and legs. But there are small muscles in your face as well.

Can you tell me about my treatment options for relapsing remitting multiple sclerosis?

DEAR DOCTOR K: I was recently diagnosed with relapsing remitting multiple sclerosis. Can you tell me about my treatment options?

DEAR READER: Multiple sclerosis (MS) is a disabling illness that affects the brain and spinal cord and worsens over time. MS damages nerve cells and a substance that is wrapped around the nerve cells, called myelin. A nerve cell functions like a copper wire -- it transmits electrical signals. Myelin is like the insulation surrounding a wire. It helps the electrical signal get transmitted down the nerve cell. When myelin is damaged, that transmission is interrupted.

What causes peripheral neuropathy and what can I do about it?

DEAR DOCTOR K: I have peripheral neuropathy. I know that people with diabetes often get neuropathy, but I'm not diabetic. What else can cause this condition? And what can I do about it?

DEAR READER: Neuropathy is a medical term that means nerve damage. The type of nerve damage that people with diabetes get involves specific nerve fibers in all nerves, particularly the nerves that travel to the legs and feet. (There are other conditions in which a single nerve leading to the legs and feet is pinched, causing pain. An example is what is often called a "slipped disk" or "herniated disk" in the lower part of the spine).
