When nerves are “pinched” by scar tissue or tight muscles and connective tissue, they are basically being suffocated. There is decreased circulation, and therefore, the nerve doesn’t receive the appropriate amount of nutrition. This is thought to be the cause of nerve pain (neuritis). With the use of ultrasound imaging, the area of nerve impingement is visualized. A needle is then placed adjacent to the impingement, and a solution of anesthetic with saline fluid is injected to separate the nerve from the surrounding tissues. By releasing the pressure from the nerve, circulation is restored, plus there can be immediate relief of pain.
