Hey guys so for the last week and half almost I have been experiencing stomach pain. This is a first for me and I have never had something like this before. Basically what is happening is I am getting pain in my stomach area that does not seem gas related or constipation. I have been taking Pepcid AC for the past week and it seems to go away for about 10 hours and then comes right back. It is a very uncomfortable pain. I am 23 years old and used to drink a lot of diet soda, almost 6 cans a day. I have a feeling it could be a possible stomach ulcer even though I have never had one ever. I tried even taking an ex-lax to see if it was constipation and the pain still came back. I have noticed that my stoles have been harder and somewhat discolored. I am getting health insurance in less than 15 days but I feel taking pepcid that long could be harmful. Please provide any help or ideas. I also fear the fact of possibly having to get a camera down my throat....
