hi i am AAAAA and i am 21 years old, i have been experiencing pain in my joints and muscles for over four months and it is getting to the point of pain killers not having an affect. the pain and aching is mainly in my back, hips, knees and thighs, but recently it has spread to my shoulders, ribs, neck and arms. if i am not in pain, then i either ache or my muscles feel sore. Any Ideas?
