In my case, because of a broken femur and resulting bursitis, coupled with the inability to take any of the normal medications to treat the bursitis, I either have to take the stronger pain meds, or live with the pain. I chose the latter. I cannot take the normal medications or any NSAIDS due to blood thinners and other issues.
I’d give cannabis a try as a substitute for the highly toxic and addictive pharmaceutical solution. It may not be enough in your case but if it is you can save yourself a world of nasty side effect trouble. I know quite a few people who have successfully made the transition and every one is extremely pleased with the difference in quality of life.
