I’m interested in your comment. I’ve had fibro 40 years and no one understands that exercise gives me flu-like aching. There’s a name for it now: post-exertion malaise. My left knee wants to buckle - been doing that for several years and I had PT to strengthen. Stopped exercising, but need to really lose weight, so started a couple months ago in a warm water therapy pool. Behind the knee area became inflamed and I couldn’t walk. X-rays show bone on bone knee OA and I have ortho app’t next week. Also have idiopathic peripheral neuropathy, with numbness in the side shin. And, lol, a couple years ago, when knee buckled going up steps carrying something heavy, imaging showed my kneecap is 2 bones held together with connective tissue, not one. That gets inflamed, too. While waiting on the ortho app’t over the last few weeks, I’ve been resting and doing some leg strengthening exercises - not the repetitions usually prescribed by PT - and I can now do household chores, stroll around big box store for 30 min…average 4K step per day. No pain meds or muscle relaxers, so I don’t think I need to start knee injections. I am scheduled to start PT and am worried, because after PT, I’ll probably be in pain and won’t be able to walk. Has that been your issue, too? I seem to be relatively pain free if I don’t exercise..but that’s not helping the weight issue. I’m 75, so surgery may not be something I want to risk. Thanks!
