Just wondering if anyone with Aps and joint and muscle pain uses a Tens machine. I usually find exercising lessens the pain in my joints immensely but currently have a horrendous pain in my right knee. It came on one night about a month ago and is getting worse if anything. I've seen the Gp who thinks it's ligament damage and the Rheumatologist thinks it's Osteoarthritis. I had an xray done yesterday but don't know the results and I'm still waiting for an ultra sound. I've been given pain killing gels and patches which have done nothing at all, well one made my leg very hot but the pain was just as bad. Tried resting, that makes it worse, tried sleeping with a pillow between my knees etc etc. It hurts if I'm sitting or laying still and wakes me up throughout the night. It's at it's worst on standing but it's not the effort of standing but trying to get my leg straight that is really excruciating and taking that first step is daunting at best, once moving it eases off a bit and I have no trouble bending it etc. Although stair climbing nearly reduces me to tears. Problem is my left knee is now starting to complain along with my right hip. I do have Tramadol but they knock me out so I tend to avoid taking them. So would tens help?
