hi im 16 and for the past 4 years i would throw up my food and drinks but at first it was when ever i ate like toast and had a drink with it then it got to not only that but when i would ate tacos with a drink or if i just drink peach juices. but lately it has gotten pretty bad now its what ever i eat. for example last night i ate dinner and had water with dinner will soon as i finished i went upstairs and felt sick and threw it all up and it happen again tonight but this time i didnt have a drink with dinner i had a drink later on but i drank it pretty fast but anyway i threw everything up. its starting to scare me. and it dosent help that when im on my time of the month i get really bad back pain in my lower back. i wish this was over. like i cant even drink water some days with out wanting to throw it all up. i dont know what to do
