Yes, I certainly would too if I became that debilitated again. Not pleasant! I swim daily in our lap pool, which we heat for as long as possible (we have solar panels) and only turn off June-September during our winter here in Australia. We are fortunate to have renovated after retiring and had the good fortune to choose to spend a lump sum on the pool knowing that in our later years a pool would help keep us mobile. During my undiagnosed months of pmr I too found the pool worked but very difficult to get out off until I was on Prednisone. Like you, warm baths and showers work too. I have just started a personal Pilates session to rebuild strength as pmr has left me with some imbalances she is correcting. That is very useful and I should have started earlier to maintain strength during treatment. Good luck!
