I'm scared to try 3 again but want too. Even on 4 I have occasional shoulder pain. It is something I can deal with. My Rumy says I can do what I want and should go by the way I feel now that I have had this this long. My last sed rate in Nov. was 21 so that means thr inflammation is still there. My question is I like to go to senior aerobics and it makes me feel good afterwards. But, the day after I am hurting. Should I continue to go at a slower rate so I can loosen up my muscles or stick to just walking? Can I work through the pain and it will get better the more I do? Or, will this just make it worse? Also how can you tell if hand pain is arthritis or pmr?
