Options: You might consider visiting a pain management doc. You may also find help from a massage therapist, chiropractor, natural doc, or clinical psychologist. All have ways to work with pain and you would do well to read up / visit some until you find one you are comfortable with. You may be able to lessen or rid yourself of this. Peace and good health.
