i went thro town today with my partner and as usal my knees and legs hurt and was tired. so we got on with what we did and got into a taxi. i tried to menover my feet and legs over the middle part to get over to let my partner in and my legs just felt like a heavy weight was hanging on them and it just took all my stregnth to move them. after we got home. i was wiped out from it and took my tablets then slept for a long period of time. my question is this something i should be worried about or is it another part of having fibro?
