I have Fibro for several years. Really do not know when it started because I thought it was arthritis. I have been going to a Rheumatoligist since 1998 and he suggests doing what you feel like. Between the Fibro and the extreme arthritis there are times there are times I lay in bed. For the past few days it has been very difficult to walk. Needless to say, falling down is one of my biggest fears. I do fall probably once a month, need a hoist to get up.
