Im 16 years old and have been having horrible stomach cramps, chest pains, nausia and a dry caugh for the last 6 months straight. I cant sit still for more than 5 minutes because the pain gets extremely bad. I cant bend over to pick something up because my chest feels like its caving in. I get no more than 5 hours sleep a night and wake up in cold sweats. Everything i eat seems to come straight back up within 2 hours until im dry reaching. Ive done research and came across a mothers story that said that her 17 year old daughter had the same symptoms. She was diagnosed with Dysautonomia and Postural Orthostatic Tachycardia Syndrome. And now her daughter has to take meds everyday. Im terrified of going to the doctor but i know i need to. Does anyone have any idea what it might be? Anything even remotely close would be deeply appreciated
