For about two month now, I keep have these bad episodes of constipation where I can't poop for over a week...and every time I get rid of it, via enema or laxative, it comes back again a week later. Sometimes I'll even have diarrhea before I get constipated again. Right now I haven't gone in almost a week, again, and all my doctor tells me to use is Miralax or a stool softener. Both have worked OK in the past to temporarily fix the problem, but today, I got severe nausea and cramps with really sharp pain in my stomach. I went poop, but I have no idea why it hurt so much to take the Miralax. My doctor won't give me any other advice to fix this problem. I'm starting to get really frightened that it won't go away.
