I have done all you mention but nothing helps now, though maybe once it did, particularly very expensive due to the National Arthritis imprimatur for the courses involving immersion for exercise in 95 degree water up to the neck. I became extremely allergic to the chemicals in this pool situation, more used because during the day people who were incontinent were doing exercises for PT. I remain sensitive to too much shower exposure. I do have a good mattress. Several. I watch Netflix and Aljazeera and other streaming options. I cannot stand long enough to do much. Neuropathies from the TSS, ME, and clindomyacin abound. I spend a lot of time in my recliner and often nap there as it is a preferable angle for what ails me. I can no longer go to the sloped backyard due to dizziness. I can't do any gardening or yard work.
