Yep... I'm agreeing with the others. Take your pain meds. I took oxycodone for 9 weeks the first TKR and 5 weeks the second TKR. Some told me to try extra strength tylenol. It did nothing for me. I transitioned to Tramadol. At the end, I was just doing one before bed and one before PT - but it was terribly important to me to do my physical therapy and sleep. I don't know of anything more important during your recovery. Have you transitioned to anything after Percocet?
