Hello Team Lybrate, first of all I would like to appreciate your concern with user's queries. I am 24 years old male, my problem happened around six months past. I drunk excess amounts of beer without having proper food intake. Consequently, unfortunate to say but I should tell you this, because elders say never lie with doctors and teachers. I was drinking beer daily, on one day I vomited blood. For around one month after this happened, I suffered form mild stomach pain but I didn't consulted any medical practitioner. Since form that day it happened, gas is forming in my stomach, I am feeling uneasy in my stomach. There is something wrong that I can notice, whenever I take water I can feel their coldness inside my stomach, sometimes I get stomach pain too. I damaged my health unknowingly. Please suggest.
