I'm 17 years old, female, and have been off and on in recovery from anorexia for over 3 years. I'm just starting to recover from a relapse. I'm 5'8 and 121 pounds. I was cooking today and my lower back and legs starting aching.. Not a normal ache that you get with working out, it was like my bones were exploding very slowly (if I could describe it in any way) I ignored it and continued, and so did the pain. I took a nap, and woke up with it being even worse! The only difference is that it was in only my left leg. The main areas was my hip, the side of my thigh, calves, and extreme in the ankles and foot. I didn't sleep differently, and didn't wake up with it hurting. I just took a hot bath and that seemed to help, but I can feel it slowly creeping back up on me. Any help would be great!!!
