I am 16 years old and was diagnosed with lactose intolerance about a year ago. I had really bad stomach pains and diarrhea and lactose intolerance seemed like the problem and I was so happy to know what was wrong. Since then though I still get stomach pain and disarrhea at least twice a week. I have also recently not been able to drink caffinated drinks without getting the pains. I also sometimes experience pain under my ribs and lower back.
I know these sythmtioms dont seem to go together but I just want to know what might be up. My doctor has already diagnosed me once so I dont think he will think anything else is wrong.
