I have been having bad lower left abdominal pain for the past week and a half. I also have pain that is underneath my ribs/breasts. I ended up going to the ER last night thinking it was a kidney stone or diverticulitis. I had bloodwork done, urine sample, and CT of my abdomen/pelvis and nothing. They did a pelvic exam and I had some pain so the doctor assumed it was some type of vaginal infection (no possibly of STD's!). They also said it could be my IBS or stomach ulcer. I saw my pcp and she essentially wasn't sure. I started on IBGUARD over the counter and flaggyl for any infection. I read that can also help with stomach ulcers. So medication wise i should be covered. But my pain has become worse and it's really bothering me! My anxiety I know is not making it worse. All scans were clear but I really wanted a definitive answer. I believe I definitely have hypochondria and IBS rears it's head during these times. But my IBS usually does not present with a persistent burning stomach. Wondering if stomach ulcer is more likely?
