Sometimes i get an awful pain in my vagina while and after a bowel moment. the pain lasts for hours and i'm not sure what it is.

See answer: Your symptoms are likely related to increase tension/tightness of your pelvic floor muscles and are included in a list of various symptoms associated with a number of symptom syndromes that go by different names and likely all inter-related: pelvic floor dysfunction, pelvic floor tension myalgia, vulvodynia, ic, ibs, etc. If no underlying problems found on eval, pelvic floor physical therapy helps.
