Vegetarian male 21, so I had this stomach problem for a while, that was like for a week. The local doctor told me it was food poisoning and he gave me tablets I had been taking them. One night when I was sleeping all of a sudden my upper back and stomach started to pain, lower the heart and below the neck, it was for like 20 mins and just went down, is this some kinda sign to something or was just a muscle pull? *I kinda tend to eat lunch outside daily, kinda healthy but.
