I am afraid I know all too well about flares so I can sympathize with you. After 40 years I still haven't completely learned how to deal with them. I get frustrated that on those days I am good for nothing and have to sit in my recliner most of the day. I know not to move around and get a little exercise isn't good for me but its sure hard to when you hurt all over. I found water exercise a lot of help but unless I went every day I was right back where I was. Good thing we can comiserate here. I find the fatigue harder to handle. Good luck to you and take care!
