I do have some pain in back, worse sometimes than others, but I don't have the extreme side effects that you seem to be getting from treatment. Wish I had a suggestion, I did use pain patches given to me by a pain mgt dr which helped tremendously. I have more left to use when I need them. Don't have a lot of pain in feet, some, none in hands. Just keep asking what they can do for you.
