Top 9 Pain in the Back Side of the Forearm Causes

  1. 1.Carpal Tunnel Syndrome

    The carpal tunnel is a narrow passageway filled with ligament and bones at the base of your hand. It contains nerve and tendons. Sometimes, thickening from irritated tendons or other swelling narrows the tunnel and causes the nerve to be compressed. Symptoms usually start gradually, and as they worsen, grasping objects can become difficult.

    Early diagnosis and treatment are important to prevent permanent nerve damage. Your doctor will diagnose carpal tunnel syndrome with a physical exam and special nerve tests. Treatment includes resting your hand, splints, pain and anti-inflammatory medicines. If symptoms do not improve with these less invasive treatments, your physician may recommend surgery.

    spontaneous shoulder pain, hand weakness, wrist pain, pain in one hand, weakness in one hand
    Urgency:

  2. 2.Brachial Plexopathy

    The brachial plexus is a complex nerve network located in the upper chest deep to the collar bone, which supplies the shoulder, arm, forearm, and hand. Damage to the brachial plexus is usually due to mechanical injury or trauma, and can interfere with normal nerve function causing numbness, pain, and/or weakness.

    You should visit your primary care physician to discuss these symptoms. It is likely the doctor will perform a thorough physical exam, and in many cases refer you to a specialist, physical therapist, or both. A professional evaluation is very important, as surgical treatment might be required for a brachial plexus nerve injury.

    Forearm pain can be caused by a host of things, but is often idiopathic (without cause).

    Thoracic Outlet Syndrome is the compression of the nerves and/or blood vessels that run through the upper chest. It can occur as a result of trauma, surgery, growths in the body, or just randomly.

    You should seek medical care soon to determine whether the compression is of the nerve or the blood vessels. You may need imaging using x-rays, CTs of the blood streams, or MRIs. Treatment depends on the extent of the injury, but usually includes physical therapy. Surgical treatment may be required if a blood vessel is compressed.
