What kind of doctor treats Mononeuritis Multiplex?
A neurologist, a doctor who treats diseases of the brain and nerves, usually diagnoses and treats mononeuritis multiplex. A rheumatologist, a doctor who treats immune diseases, may also help. A direct primary care or concierge doctor can be a first stop for an evaluation and can refer you to a specialist when needed.
What is mononeuritis multiplex?
Mononeuritis multiplex is a nervous system disorder. It involves damage to at least two separate nerve areas. It is also called multiple mononeuropathy. Neuropathy means damage to a peripheral nerve. Peripheral nerves are the nerves outside the brain and spinal cord. It is a group of symptoms, called a syndrome, not a disease. It can affect both sensory nerves, which carry feeling, and motor nerves, which control movement.
Symptoms
Symptoms depend on the specific nerves involved. They may include:
- Loss of feeling in one or more areas of the body.
- Paralysis, which means not being able to move, in one or more areas of the body.
- Tingling, burning, pain, or other unusual sensations.
- Weakness in one or more areas of the body.
- Loss of bladder or bowel control, which is rare.
People with less feeling may miss bruises, open skin, or other injuries. These injuries may become severely damaged or infected.
Causes and who gets it
Certain diseases can injure nerves and lead to mononeuritis multiplex. Common causes include:
- Blood vessel diseases, such as polyarteritis nodosa. Inflammation can thicken and scar blood vessel walls. This can make it harder for blood to flow and can cause nerve damage.
- Connective tissue diseases, such as rheumatoid arthritis or lupus. Lupus is the most common cause in children.
- Diabetes.
Less common causes include infections such as Lyme disease, HIV/AIDS, or hepatitis.
How doctors diagnose it
Your doctor will do a physical exam and ask about your symptoms, focusing on the nervous system. There usually needs to be problems with two or more unrelated nerve areas. One test is an electromyogram (EMG), which records electrical activity in the muscles. Nerve conduction tests measure how fast nerve impulses move along the nerve. Blood tests and imaging tests, such as x-rays, may also be done. A nerve biopsy looks at a piece of the nerve under a microscope. It should be done only when necessary. It can further damage the nerve and cause lasting nerve pain and loss of feeling.
Treatment
Treatment aims to treat the illness causing the problem, if possible. It also gives supportive care to maintain independence and controls symptoms. Physical therapy and aids such as braces, splints, or a wheelchair may help people stay independent. Over-the-counter or prescription pain medicines may help. Opioid (narcotic) pain medicines are not recommended for pain from peripheral neuropathy. Some people with peripheral neuropathy from inflammation or an immune problem may improve with steroids or medicines that calm the immune system. Talk with a doctor before stopping any medicine. Depending on the cause, surgery may be recommended to reduce pressure on nerves.
Less feeling and poor muscle control may raise the risk of falls and injuries. Good lighting, railings, and protective shoes can help. Remove loose rugs and test the water temperature before bathing. People with this condition may be prone to new nerve injuries at pressure points such as the knees and elbows. Avoid leaning on the elbows or crossing the knees for long periods.
When to see a doctor
Contact a doctor if you notice signs of mononeuritis multiplex, such as the symptoms listed above. Call 911 or go to the emergency room if you have sudden weakness, trouble breathing, a change in mental status such as confusion, or you cannot speak.
How a direct primary care or concierge doctor fits in
A direct primary care doctor charges a flat monthly fee instead of billing insurance, while a concierge doctor usually charges more and often works alongside insurance. Such a doctor can review your symptoms, order first blood tests, and refer you to a specialist. They can also help with long-term follow-up.
Common questions
Is mononeuritis multiplex a disease?
No, it is a group of symptoms, called a syndrome, not a disease. Certain diseases can cause the nerve damage that leads to it.
Can people recover from mononeuritis multiplex?
Yes, in some cases. A full recovery is possible if the cause is found and treated and if the nerve damage is limited. Others have a partial or complete loss of movement, function, or sensation.
Does mononeuritis multiplex affect only one nerve?
No, it damages at least two separate nerve areas. Common nerves affected are in the arm, shoulder, hand, thigh, and leg.
Can mononeuritis multiplex be prevented?
It depends on the cause. With diabetes, healthy eating and tight blood sugar control may help prevent it.
