Hi everyone, newbie here, although have been reading your posts for quite sometime as fibro was first mooted as a possible reason for all my symptoms about 5yrs ago. I get the fatigue, brain fog, the ceaseless pain in back and legs and arms preventing sleep, but I am also now getting spontaneous knee pain, which feels like a knife being driven through my kneecap, and accompanying swelling. When I've been to gp to query this I'm told that I've obviously injured my knee by banging into something or twisting it during exercise etc, no way will they believe that this has occured spontaneously, often overnight when I'm doing nothing more strenuous than lying in bed trying to sleep! Has anyonr else had this problem, and if so any suggestions for easing the discomfort? Thanks in anticipation!
