12 year old female, no real medical history until 9 months ago. Pain started in left rib about 9 months ago, came and went at night. Then came back over the summer. X rays showed nothing abnormal. Then about a month ago pain in lower right abdomen, that then spread across the abdomen. Blood tests, MRI, x-rays, ultrasound all normal. Pain then started in the chest, EKG and subsequent blood tests/ultrasound/X-rays still normal. Rib pain and abdominal pain comes and goes, chest pain is gone. Then about 2 weeks ago persistent headache and neck ache started, rib pain and abdominal pain still there, Lyme and lupus tests came back negative. OTC painkillers don’t help. Prevacid didn’t help. Waiting for some results from gastroenterologist. Any ideas of what this could be?
