13 year old female. 5"2' and 185 lbs. Has ongoing pain in left upper abdomen that radiates to back on left side. Gallbladder was removed via Laparoscopic surgery 6 weeks ago. When she woke up from surgery, she said that terrible pain where her gallbladder was is gone, but her lower back was extremely painful and has continued. This pain was there slightly after surgery but progressed and has seemed to spread. Pain is described as a stabbing pain and is now feeling like it moves around the abdomen and lower back with stabbing pain in different areas. CT, Blood, x-ray and Laryngoscopy and colonoscopy all negative. No fever either just nausea. She can eat but makes pain worse. She spent 5 days in the hospital trying to find the cause to no avail. She is tired all of the time because she can't get enough rest. She is awakened at night from pain, moans in her sleep and tosses and turns, which is all abnormal for her. She has always gone to be early as her own preference, now she can't sleep. She is not comfortable whether lying down or sitting. She has chills at times as well. All blood tests show negative for: Pancreatitis, Mono, Ciliacs disease, Her GI doctor thinks it may be IBS, but she never had that before surgery or any of the symptoms. Any ideas?
