I am post menopausal and have been active all my life but now I find I am awakened at night by pressure on my vagina from the rectum. Although I feel I need to have a bowel movement I am unable to and am repeatedly woken with the same sensation. In the morning I eventually have a BM and feel some relief but today, in spite of having several BMs I feel pressure on the vagina and am having difficulty walking as I am so uncomfortable.
