My 16 year old daughter has had a lot of pain, sometimes severe on her right side mid way between ribs and hip. Initially it was thought it could be appendicitis and she underwent observation for that. She then had a feces specimen checked at lab as I mentioned that we had been in Indonesia about 4 months before pain started. Sample showed she had blastocystis hominis (SP?). She also had an ultrasound of her abdominal area which showed mesinteric adenitis (SP?). She has undergone antibiotics (two types) and we have recently been back to doctor as 6 months after first visit she still has the pain. More samples sent to the lab which came back clear but it could be that the doctor didn t ask specifically for a blastocystis check just parasite . Doctor now wants my daughter to go on the pill as a tool for diagnosing whether or not her ovaries are the problem. I am confused and a bit disillusioned. Any ideas?
