I have CIPD and am in chronic pain as well...I take oxycod Q4 hrs which seems to control some of it (until the third hr which is heck)...it took several pain specialists to find something as simple as this...keep trying and see if there is anyone in your area that has had success with a pain specialist...personal referrals seem to be the best way to go...hope you find some relief..I know that it is all consuming and changes everything about one's life...all the best
