For the past 4 days I have had a very small amount of diarrhea every time I have urinated. Starting yesterday I've been having cramps when I use the bathroom. Then today after I ate i was having really bad cramps but nothing would come out. After the cramps were getting worse I was able to have a bowel movement that relieved the cramps alot, but not completely. At first I thought all this was something I ate but after 4 days I'm starting to get concerned. I've never had anything like this. If it lasts for more than a week I'll go to the doctor. What do you guys think?
