First, nerve pain can be caused by a tissue that pinches on it. This could be a herniated disc, a muscle spasm, or arthritic changes in the spine. Such treatments as mechanical traction or soft tissue massage around the pinched area of the nerve can alleviate the nerve pain.
Second, the nerve itself can become injured. Physical Therapists use manual therapy techniques to mobilize the nerve itself to reduce its pain and improve it mobility. Similar to having a knee surgery, it is important to calm the swelling and pain down while progressively improving the range of motion back to its normal length. Nerve is just as much of a connective tissue as ligaments or tendons are.
Lastly, when nerve pain occurs it becomes inflamed, a term called neurogenic inflammation. Like a hose spraying with water, when the nerve is inflamed it sends inflammation to its termination sites – such as muscle, joint, or ligaments. It is important to improve muscle or joint restrictions that surround the nerve to fully treat the nerve pain and its residual effects.
