Stomach Pains

:d hi my 15 year old daughter had strep throat 1 month ago. She was put on a antibiotc. This was only the second time in her life for a antibiotc. Her symptoms went away although another swab indicated the presence of strep, but she had no symptoms. At the same time she developed pain on her left side just below the rib cage. We have recieved opinons like ovarion cysts of which she is booked for a us but not untill jan. They put her on mefenamic 250 mg. But when she takes it it gives her pains similar to gall bladder pains. In the mean time this pain as migrated to the right side and back again. This is what made them think it was cysts I am wondering if the strep she had could have any bearing? She has had all the blood tests. Mono, etc. Yesterday she woke up crying with it. We tried to see a doctor, but in this town it is impossible. Could my theory be right? All people that had this flu and then the strep seem to take a long time to recover. Like I said before she has not been sick other then when she was 3 with tonsillitis. Any inf would be great. Thanks patsy
