Hi Tina,
have you tried something like prune juice?...this may well soften up your bowel movement enough to allow you to pass it without as much pain. Be careful not to take too much to begin with or you could end up with 'the runs', some people are quite sensitive to it (I am!).
If you are taking a fiber supplement, make sure you are drinking enough water too otherwise the fiber will cause you to 'clog up'.
Hope the info helps...let me know how you get on

Good luck!
