I have found that 15 minutes in a steam sauna 3 or 4 times a week helps with relaxation and improves my overall sense of wellbeing, but has not seemed to alter the course of my pmr symptoms. (First attack, age > 70, prednisone at 20 mg started 10 months ago with almost complete relief in 48 hrs, tapering by 2.5 mg/mo to 10 mg, then by 1 mg per month. Flared at 5 mg, resolved with increase to 7 mg, now at 4.5 mg and am tapering by 0.5 mg every 4 to 6 weeks. Still have mild pains in shoulders, about 1/10, but only with exercise and not at rest). Best of luck to you, wish you a lasting remission.
