I've been like this since I was a senior in high school. I'll be very blunt it started with a lot of bloated stomach, pains and gas. It got to the point of embarrassment that I hated to go to school. I was even ashamed to tell my mother. It seems to get worse around my periods. I just put up with it and went on with my life. I've always had bouts of constipation and then when the stomach pains came so did the diarrhea. 4 years ago I decided to go to a specialists and had tests done. At that time I found out I was lactose intolerant. So I watch what I ate and started on the lactaid pills. It was fine for awhile,I still had pains. Within the last year I've had 4 episodes where after I ate the stomach cramps were so umbearable. Diarrhea like crazy with pain then I would be alright if I didn't eat anything. Then the next day be scared to death to eat, so I wouldn't. It does seem to get worse when things are messed up in my life. Could this be crohn's disease? I know my Aunt had part of her intestines removed a few years ago. Thank you for your opinion and what should I do next? See a doctor or just go on like I've been for 40 years.
