Hello. I am 76 years old and a recent immigrant from north-east China. I have lower abdomen pain and comes and goes, but happens daily for weeks at a time and lately won't seem to go away. I experience periodic dizziness, generally feel bad/weak sometimes. Other than that, I don't have any other symptoms. The pain is so severe that it makes me stay in bed all day sometimes. I have been to the doctor and they have run many tests with no luck in finding out what the cause is. They have run xrays and an mri, and still found nothing wrong. My main diet is seafood, vegetables, and pork. I do NOT have blood in stool NOR painful urniation. As far as I can tell there are no other symptoms. We did not used to be so careful cooking pork fully, so I'm wondering if this could be trychinosis? Chrones disease? B12 deficiency? (I take a daily multi-vitamin sometimes) Any other ideas what can cause this kind of pain but not show up in typical blood tests, xray, and MRI? When I was in China they were treating me with a long term antibiotic, but I don't know what it is in english and I'm not sure if they were accurately treating me anyway (medicine there is not as up to date as it is here and staff are not trained as well as they are here). I read once about a bacterial infection one can have in their intestine that sounded similar to this, but I can't find the name of it again. Do you have any ideas? The pain is so severe it makes me feel horrible most of the time with only periodic short-term relenting. I have been taking darvocets, but even they don't help much. I tried wine, but that didn't help much either.
