Nerves are like electrical wires that transmit signals between the brain, skin, and muscles. These signals allow your brain to control muscle movements in the hand and arm. Signals to the brain from the skin and tissues in the hand allow sensations such as pain, pressure, texture, and temperature to be felt.
Symptoms of tingling, numbness, weakness, burning sensations, or pain in the hand, forearm or arm usually mean there is a problem with one or more of the following nerves:
- Cervical spine
- Brachial plexus
- Median nerve
- Ulnar nerve
- Radial nerve
- Other small nerves
Specific conditions like carpal tunnel syndrome, cubital tunnel syndrome, thoracic outlet syndrome (compression of nerves near the shoulder), lacertus or pronator syndrome (compression near the elbow), and radial tunnel syndrome (affecting the radial nerve near the forearm) are also common causes of persistent elbow, forearm or hand pain.
Nerve compressions such as carpal tunnel syndrome, cubital tunnel syndrome, thoracic outlet syndrome, lacertus or pronator syndrome, and radial tunnel syndrome can sometimes be treated successfully with physiotherapy and changing lifestyle and workplace factors. Surgical decompression to permanently loosen the nerve is also a very safe option which gives rapid, long term relief especially if symptoms persist or if changing lifestyle and workplace conditions are not feasible.
Nerve injuries, compressive nerve disorders, or nerve tumours, may require surgery to restore normal function. This involves relieving pressure on the nerve, removing abnormal structures, or repairing the nerves.
When nerve function is impaired due to inflammation or infection, direct nerve repair may not be possible. Nerve or tendon transfer surgery can often improve the function of the hand and arm.
