Brachial plexus injuries :
The brachial plexus is the group of nerves that are involved in sending signals from the spinal cord to the hand, arm, and shoulders. The injury caused to these nerves when they are stretched, squeezed, or torn apart from the spinal cord is called a brachial plexus injury. These nerves may also get damaged during cancer radiation therapy. Rarely does this injury also occur during childbirth. There are many types of brachial plexus injuries depending on the severity of the nerve damage. Those types are brachial plexus neuropraxia, brachial plexus neuroma, brachial plexus rupture, brachial plexus avulsion, and brachia neuritis. The symptoms of this injury can be numbness of the arm or hand, difficulty in movement of shoulder or arm or hand, sudden and severe pain in the arm or shoulder which is also burning pain. This injury can be diagnosed through X-ray, CT scan, or MRI scan and treatment options can be physical therapy such as exercises, corticosteroid injections, medications, assistive devices, and occupational therapy. When this injury does not heal by its own, surgical treatment is required to repair the damage.
