i am 19 years old and i weight lift and run regularly so i am always in great shape and have no allergies at all. i am in the process of joining the marines and i need to be perfect health for my meps physical. i have recently started having a problem with my throat and stomach. i always have mucus in the back of my throat wheather its after i eat, drink or am doing nothing. its to the point where after i eat i feel the food rising from my stomach half digested and it usually leads to vomiting. this is really effecting me because i cant even talk to someone because in mid conversation i feel like i have to gag. when i gag i burp because recently i cant burp on my own i have to gag to get air up. i have no health insurance due to no longer being in school so thats why i came to this post. i know this is a very hard subject to analyze due to me reading numerous post from other people with a similar problem. i would be very humble to anyone who can guide me in the right direction because i am very anxious to go to the military.
