what can i do

recently i have been having stomach problems, i was taking ampicillin which iam allergic to, after that i was taking levaquin for what i dont know thats what the doctor perscribed; mind you i went to a obgyn first(ampicillin)i was later infected because of allergy, then i went to a throat doctor which gave me (levaquin), after that i felt like my heart was going to explode i had rashes all over me, dry throat. which caused major stress. well what im trying to get at is nothing seems to be digesting medication , food nothing. i have to take a laxative every day dependability on the foods i eat for that day, if i eat something fairly light i can go for about 2 days, my chest feels infected, or pressure i cant seem to figure it out, and the doctors cant seem to either. should i just be refered to a specialist because the last drug the doctor put me on was prosilec and it wouldnt digest please give me some clues. keke
