Peripheral Nerve Disorders: Causes, Symptoms, and Treatment

What kind of doctor treats Peripheral Nerve Disorders?
A primary care doctor is often the first doctor people see for nerve symptoms. When the cause is unclear or symptoms are severe, they usually refer the patient to a neurologist, a specialist in the brain, spinal cord, and nerves.
What it is
Peripheral nerves sit outside the brain and spinal cord, carrying messages between the central nervous system and the rest of the body. A peripheral nerve disorder happens when these nerves get damaged or stop working properly; doctors often call this peripheral neuropathy.
Symptoms
Symptoms depend on which nerves are affected. Common symptoms include numbness, tingling that feels like pins and needles, burning pain in the hands or feet, and muscle weakness or balance problems.
Causes and who gets it
Diabetes is the most common cause of peripheral nerve damage in the United States. Other causes include injuries, infections such as shingles, autoimmune diseases, some chemotherapy drugs, and heavy alcohol use. In some cases the cause is never found, which doctors call idiopathic neuropathy.
How doctors diagnose it
A doctor starts with a physical exam and a health history, and may order blood tests to look for causes like diabetes or vitamin deficiencies. Electromyography (EMG) measures electrical activity in your muscles, while a nerve conduction study checks how fast signals travel along your nerves.
Treatment
Treatment focuses on the cause and on easing symptoms. For people with diabetes, keeping blood sugar in a healthy range can slow further damage. If a vitamin deficiency is the cause, replacing that vitamin may help. Physical therapy can improve strength and balance, and medicines can reduce nerve pain.
When to see a doctor
Talk to a doctor if you have ongoing numbness, tingling, burning pain, or muscle weakness that does not go away. Seek care quickly if symptoms come on suddenly, spread quickly, or come with trouble breathing or swallowing. Early evaluation gives the nerves the best chance to recover.
How a direct primary care or concierge doctor fits in
A direct primary care doctor is one the patient pays with a flat monthly fee instead of using insurance for visits. A concierge doctor works similarly but usually charges more and often works alongside insurance. They can manage many cases directly, especially when the cause is diabetes or a vitamin deficiency, but would refer severe cases to a neurologist.
Common questions
Can peripheral nerve damage go away?
Some nerve damage improves when the cause is treated, especially if it is caught early. Nerves heal slowly, and recovery can take months. Severe damage may not fully recover, so results differ from person to person.
Is peripheral neuropathy the same thing as a pinched nerve?
No. A pinched nerve usually affects one nerve in one spot, often in the neck or back. Peripheral neuropathy usually affects many nerves at once, often in the feet and hands.
Can peripheral nerve disorders be prevented?
Some cases can be lowered by controlling diabetes, limiting alcohol, and avoiding injuries. Not all cases can be prevented, since some causes are unknown or inherited.
Do I need to see a neurologist right away?
Many people start with a primary care doctor, who can run basic tests and treat common causes. A referral to a neurologist makes sense when symptoms are severe, unusual, or do not improve with treatment.
