What kind of doctor treats Brachial Plexopathy?
A neurologist (a nerve doctor) treats brachial plexopathy. Some bad cases need a nerve surgeon. Physical therapy often helps recovery. 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 brachial plexopathy?
Brachial plexopathy is damage to the brachial plexus. The brachial plexus is a network of nerves. It runs from the lower neck through the upper shoulder area. These nerves let the shoulder, arm, and hand move and feel. Damage causes pain, less movement, or less feeling in the arm and shoulder. Doctors call it a form of peripheral neuropathy. That means disease of the nerves outside the brain and spinal cord.
Symptoms
Symptoms depend on which nerves are hurt and how badly. They may include:
- Numbness of the shoulder, arm, or hand.
- Shoulder pain, or tingling, burning, or other odd feelings where the injury is.
- Weakness of the shoulder, arm, hand, or wrist.
- A limp or paralyzed arm in bad injuries.
An exam can also show weaker arm reflexes. It can show muscle wasting too. That means the muscles shrink from lack of use.
Causes and who gets it
Common causes include direct injury to the nerves. Stretching injuries are another cause. These include stretching during birth. Tumors can press on the nerves. Lung tumors do this most often. Radiation therapy can damage the nerves.
Falls, car crashes, and athletic injuries can also cause it. The nerves can be stretched too far. Swelling of the nerves from a virus can cause it. So can an immune system problem. Birth defects that press on the neck can too. Toxins and certain medicines can as well. In some cases, no cause can be found. Diabetes and kidney disease can damage nerves. One rare type is Parsonage-Turner syndrome. It is seen more often in young and middle-aged men.
How doctors diagnose it
A doctor examines the arm, hand, and wrist. The doctor asks about your history. Tests may include EMG. EMG is a test that checks the muscles and the nerves that control them. Nerve conduction studies measure how fast signals move through a nerve. An MRI scan takes detailed images of the head, neck, and shoulder. Blood tests or genetic tests may be done when needed.
Treatment
Treatment aims to fix the cause. It also helps you use your hand and arm. Some cases get better on their own. Options include medicines to control pain. Physical therapy keeps the muscles strong. Braces, splints, or other devices can help you use your arm.
A nerve block injects medicine near the nerves. This reduces pain. Surgery can repair the nerves. It can also remove something pressing on them. If diabetes damaged the nerves, treatment also aims at the diabetes. Some people need occupational therapy. Counseling about work changes can help too.
When to see a doctor
See a doctor right away for pain, numbness, tingling, or weakness in the shoulder, arm, or hand. This matters most after an accident, a fall, or a stretch injury. Call 911 or go to the emergency room right away if weakness comes on suddenly, you have trouble speaking, or you have a head, neck, or spine injury. Sudden, severe pain in the shoulder or arm is a warning sign. It needs prompt care. Nerve injuries can worsen or become permanent without treatment.
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. Either can check a new arm or shoulder problem. They can order early nerve tests. They can arrange physical therapy. They can follow your recovery over time. They can arrange care with other doctors.
Common questions
Can brachial plexopathy heal on its own?
Yes, some cases do. Some injuries may heal without treatment. Babies hurt during birth often improve by 3 to 4 months of age. A good recovery is possible when the cause is found and treated.
What is Parsonage-Turner syndrome?
It is a rare, inflamed form of brachial plexopathy. It causes severe shoulder pain without any injury. Researchers think most cases come from an immune response to a trigger. A recent viral illness is the most common trigger. Men get it more often. It usually starts in young or middle age.
When is surgery needed?
Surgery is needed in some severe cases. One case is a nerve torn partly or fully away from the spinal cord. Surgery can also remove something pressing on the nerves. A nerve surgeon decides based on test results.
How long does nerve pain last?
It depends. Nerve pain may be severe, and it may last a long time in some people. Treatment focuses on controlling the pain while the nerves recover. Medicines, physical therapy, and nerve blocks can help.
