Are you having any bleeding? Can you feel them? (I know--not the most exciting thing to try to do.) There are internal and external ones. I've had both. So, you can get internal suppositories as well as external cream.

Yeah, diet is important. You need to have loose enough bowels, so you don't have to strain when going to the bathroom. So, a stool softener can help, especially if they are internal. I've had really painful ones, too. And bad external ones after delivering my first baby. (The second one was done by c-section, so at least I didn't have to worry about them after his delivery.)

I don't know about yeast infections related to them. But if these tactics don't work, then that could be the cause.

Good luck! Talk about pains in the posterior......Groan.
