I haven’t tried hydrotherapy. Is that something I should ask my physio?
Yep. I was diagnosed back in 1997-8 with chronic inflammatory arthritis, HLA-B27 marker suspected spondylitis, but affected mostly my feet and ankles (disregarding referred pain), the pain and swelling was ridiculous – wheelchair bound for two years and many subsequent years on crutches.
The only thing that worked for me at the very worst times was hydrotherapy, it was instrumental in maintaining a degree of mobility as the temperature of water and the afforded increase in movement can be profound. Arthritis stiffens muscles and you get into bad posture habits which can become an endless aggravating cycle.
I also took very hot baths each and every day, one morning, one evening. This was the only thing that worked at the time, to loosen up, lessen the pain. Contrast baths also worked. Alternate hot and cold packs should have a similar effect. Ymmv of course. Yes talk with your physio re hydro. I also used epsom salts in a hot bath, lots of it. Had to sign a disclaimer at the chemist that I wasn’t going to use it to make bombs (seriously!)
Arthritis Research UK recommend hydrotherapy for AS. Of course see your rheumatologist re injections, it may not be just one thing that works for you but lots of approaches. Best to use physical therapy whether you take drugs or not. I chose a largely drug-less route (except for NSAIDS) but it was/is sometimes very hard work. All the best keep at it til you win.
