5 Possible Significant Loss Of Muscle Mass In One Arm Causes

The list below shows results from the use of our quiz by Buoy users who experienced significant loss of muscle mass in one arm. This list does not constitute medical advice and may not accurately represent what you have.

Brachial plexopathy (shoulder nerve issue)

The brachial plexus is a web of nerves between the neck and shoulder, connecting the spinal cord nerves to the arm. There is one web on each side of the neck. Any injury that forces the shoulder to stretch down, and the neck to stretch up and away, can damage these nerves and cause brachial plexopathy.

Sports injuries and car accidents are often involved. Inflammation, tumors, and radiation treatment can also damage the brachial plexus.

Milder symptoms include numbness and weakness in the arm, with a shocklike stinging or burning sensation. A more severe injury can cause paralysis and loss of feeling in the arm, with pain in some parts of the arm, hand, and shoulder.

These symptoms should be seen by a medical provider since permanent damage can result if the injuries are not treated.

Diagnosis is made through electromyography (EMG) testing, CT scan, MRI, and sometimes angiogram.

Treatment usually involves rest and physical therapy. Surgery may be necessary to remove scar tissue or repair the damaged nerves.

Rarity: Uncommon

Top Symptoms: pain in one arm, shoulder pain that shoots to the arm, arm weakness, numbness in one arm, shoulder pain

Symptoms that never occur with brachial plexopathy (shoulder nerve issue): pain in the front middle part of the neck

Urgency: Primary care doctor

Chronic idiopathic peripheral neuropathy

Peripheral neuropathy refers to the feeling of numbness, tingling, and pins-and-needles sensation in the feet. Idiopathic means the cause is not known, and chronic means the condition is ongoing without getting better or worse.

The condition is most often found in people over age 60. Idiopathic neuropathy has no known cause.

Symptoms include uncomfortable numbness and tingling in the feet; difficulty standing or walking due to pain and lack of normal sensitivity; and weakness and cramping in the muscles of the feet and ankles.

Peripheral neuropathy can greatly interfere with quality of life, so a medical provider should be seen in order to treat the symptoms and reduce the discomfort.

Diagnosis is made through physical examination; blood tests to rule out other conditions; and neurologic and muscle studies such as electromyography.

Treatment involves over-the-counter pain relievers; prescription pain relievers to manage more severe pain; physical therapy and safety measures to compensate for loss of sensation in the feet; and therapeutic footwear to help with balance and walking.

Rarity: Rare

Top Symptoms: distal numbness, muscle aches, joint stiffness, numbness on both sides of body, loss of muscle mass
