I've just read a number of posts about fatigue. I definitely do not have that problen but there is another one. I always feel very stiff, worst when I wake up. I do exercises to try and keep me supple especially my legs but its definitely getting worse. I can no longer run or take stairs two at a time. My hamstrings are getting tighter and my thighs just generally ache and that is all the time. Does anyone else get incredibly stiff and have you any solutions?
