Girlie, it is not stomach pain. It is intestinal pain, stomach pain doesn't result in diarrhea and fever. More so, anta-acids don't help, at least not when it got really bad.
I take 200 mg twice a day, but after 10 days of resting, I started only 200 mg a day and it was enough to feel mild burning in my abdomen (took it with a lot of food and probiotics an hour prior). Also, when I defecate, my anus hurts a little, probably from the hard constipated stool(sorry if this was horrible info). Is it inflammation in the bowel? Might be, however there is no blood, so no Crohn's or Ulcerative Colitis.
I had stomach pain when I took Mepron...that resulted in diarrhea shortly after.
If you're convinced it's from the doxy...then you should stop taking it. Give your GI a rest. It may take longer than 10 days.
So, you had diarrhea, now you're constipated?
