I am currently 11 weeks out from total knee replacement and am having a lot of pain from muscle cramps or spasms in and around my knee. It started after I withdrew from Hydrocodone and had diarrhea for a few weeks. I have had massages, my PT has done ultrasound and TENS. We have babied the leg along by slowing down to nothing on exercise. I am taking muscle relaxers when there is a flare. Thought I was out of the woods last week and started to begin low level of strengthening exercises. After a few days, knee is now is spasm again. Doc put me on Potassium supplements late last week as tests proved slightly low. I am the same person who at 6 weeks out was ready to be released because I had terrific movement and gaining strength. What a mess. My Orthos have pronounced that despite my current symptoms that the knee has healed beautifully and is functioning properly. How can I regain my former health?
