I am 15 years old and am on holiday in Turkey. 3 days ago I got a terrible headache mostly on my fore head but occasionally spreading. After a little while I started throwing up like ever 3-5 hours. I wen to the hospital a day after it started and was put on a drip after some blood tests they ruled out infection and sent us home saying it was heat exhaustion. It has been a day since and I feel no better despite my medicine. I have not eaten anything since it started. My dad is convinced it it heat exhaustion but I am not so sure, he says I have to drink a lot of water but I throw most of this up. I am lying down on a bed in a cold room with all curtains closed. Can somebody please help? Do I have heat exhaustion or something else? ( the only experience I have had with headaches are sinuses)
