Hi, my 15 year old daughter is complaining of nausea, dizziness, says stomach feels warm, hot and cold and shaking also is not sleeping very well. This has been going on for months we can't figure it out, she is not sexually active and doesn't do any drugs also is not stressed or anything, she is very happy kid. I don't know what to do anymore please help me if you can, I can't take watching her go through this anymore, it's an awful feeling not being able to help her.. Thank you so much
