my daughter is 16...she is having what she describes as severe pain on her left side at her ribs, about 10 inches below her armpit....it hurts when she breathes and the pain is moving down her back, butt, leg. She says it hurts all over now and she has had a headache for a few hours. I have asked her if it is time for her cycle, she says no. she tends to panic at every ache or pain, so I have suggested she try stretching and taking deep breaths to see if helps if it is a muscular thing...this has not helped.
