When i was a teen i had a lot of stomach aches for unknown reasons. I also had some "heartburn". I had been to a few Dr.s for it and had many tests done to see if there was a ulcer etc. and there never seemed to be any problem, but the one Dr. said i am going to treat this as if you do have an ulcer and he prescribed Zantac. Poof....pain completely gone . The Zantac worked for years but stopped working for me at some point so i was switched to Prilosec and that did wonders for me also. Then my insurance told me they will no longer pay for it and i was switched to Prevacid and that is what i am currently on for the past 5 or 6 years now.
