I am asking on behalf of my 17 year old daughter.She suffered a burst AVM 12 years ago, that s when all the problems started. Later she was diagnosed with Hashimoto s for which she takes synthroid.....Later around 12 years of age she was diagnosed with PCOS, for which she is on many hormone regimens to help with symptoms..Two years ago she had seizures, and had been prescribed Keppra, which she is on til date. Now the main problem, My daughter has not been having extreme tiredness, stomach aches,localized back aches and constant nausea. No endocrinologist, rheumatologist or even her gynec has been able to diagnose her. we end up with her internist over and over again. We changed her internist but no avail.. HELP!
