spiker, I *feel* your pain......
Pain strikes when it wants to, besides PMR type aching, I have Baker's cysts. Neither of these conditions respond well to exercise most of the time, whether it's walking or lightly strengthening. I can tell my body misses and needs to work out as I've done for decades and decades. Today, I will really suffer as I did, at low intensity, a Bone Building class I've done since 2017. Of course, this curse sidelined me from doing anything physical starting in Jan '24 but I decided to go ahead and work out anyway...lighter with strengthening and no jumping around with cardio. Whether I hurt or not. My take is that I'll just see what happens.
I do wish you the best, not sure what I'm doing is a good thing....prob really increasing the inflammation. Who knows. I do not take steroids. So there's that.
