I have been experiencing pain in my knee about every other day.I also have stiff sore legs in the morning and find it difficult to walk.My legs get so cold sometimes it hurts right down to the bone.When I was younger I also had a few problems like if I sat on the floor for a bit and tried to get up I couldnt feel my legs and when I would take a step I would fall down.I just marked it as poor circulation.I take tylenol 650mg about everday and have complained of the knee pain they prescribed me naproxen and it doesnt seem to do anything.The heating pads and blankets are my best friend but dont always take the stiffness or soreness away.Has anyone had these same problems?How did you deal with it and was you diagnosed with anything?What test can be done to tell me what is going on?Can bloodtest tell me or x-ray?I cant afford any expensive testing,your opinions are welcome thanks.
