My doctors have had me on either Oxycodone or hydrocodone since I herniated disks in my back in 2000. I haven t done anything to overuse anything, and I ve developed severe tendonitis in both wrists (I had surgery on my right wrist last year 8/14), and my left elbow. Since my wrist surgery last August, the popping and pain has returned, and I m having surgery on my left elbow next week. I m wondering if the tendonitis could have developed from taking Oxycodone, because I haven t a clue how it developed.
