I have 3 different forms of arthritis. Pain, for me, comes in the form of flare-ups, each flare leaving more joint damage & less range of motion. My chiropractor recommended infrared heat, and only after a couple of infrared sauna sessions, my joints have loosened that I didn’t realize were stiff & my knee is much better. After 6 sessions, I could almost make a fist. Now I can wear my wedding ring for the first time in years.
