When nerves are “pinched” by scar tissue or tight muscles and connective tissue, they are basically being suffocated. There is decreased circulation and the nerve doesn’t receive the appropriate amount of nutrition. This is thought to be the cause of nerve pain. Using ultrasound, the area of impingement is visualized. A needles is placed adjacent to the impingement and fluid is injected to separate the nerve from the surrounding tissues. By releasing the pressure on the nerve, circulation is restored and there is immediate relief of pain.
