There are many types of nerve compression syndromes that can cause chronic pain. Some patients may respond to an injection of steroid or dextrose around the compressed nerve and/or the injection of a large amount of fluid to "stretch out" the space around the nerve called hydrodissection.

The most common form of nerve compression is Carpal Tunnel Syndrome. This is caused when the median nerve in the wrist is compressed causing tingling, numbness and pain in your hand, and especially night pain. Another common syndrome is meralgia paraesthetica which is when a nerve to the outer thigh is compressed in the groin.
