For the past month or so I have had terrible stomach pains they are lower near my navel it causes me to go to the bathroom a lot. This monday and wedesday I got sick on my stomach. Wedesday I ate frozen pizza that was cooked in the oven nobody else got sick after 2 hours of eating I was in the bathroom for 20 min horrible pain. Could this be a milk allergy? I ate some milk products today and so far so good no problems a little sour stomach but im not going to the bathroom any. But ive never had this problem before with a bad stomach all the time. Please help im clueless.
