A few months ago my daughter had rectal bleeding. it was bright red. A colonoscopy and barium enema was done. Nothing was found. About a month ago she started complaining her stomach was hurting. The upper right quadrant. She has nausea after eating. She also had a ultrasound done on her gallbladder to see if that was causing it. Still nothing found. When she was having the rectal bleeding they did a cbc on her. White blood cell count was slightly elevated. There were other things flagged also but I can't remember. She sometimes is tired, but don't know if I should attribute it to being a teen or not. She doesn't stay up late because I make her go to bed early. But she still comes home from school really sleepy and will take a one to two hour nap. Her joints will also lock up, her knees, and elbows. They sometimes stay locked up for a few minutes. Doctor said it was because she grew really fast. She is 5' 8" and 14. Any suggestions would be appreciated. And also if there are certain types of doctors I should bring her to.
