I'm 22years old I'm 5'2 I weight probably around 116 pounds. I have like a iron deficiency problem. I also have allergies to pollen, dust, animals,smoke foods such as potatoes oranges. My stomach has been bothering me alot lately. It started on the 19 of this month after i ate a store bought sandwhich i burped and it felt like i had to throw up. On sunday night i had to take some pepto bismal because i kept burping and felt like i had to throw up and my stomach feels like it tightening/pulling inward. last night i had two little pieces of chesse basil italian sausage with white bread and if felt like food was floatin or something i kept hearing a girggle noise and i drank some tree hill peach tea and also felt like i could'nt drink it that it might come back up and i keep shaking.
