The origin of the pain play the role of an edema and hyperemia of inflamed tissues and organs, leading to stretch their serosal surface of the peritoneum, covering internal genitals), compression of the nerve endings, compression and displacement of adjacent organs. A certain influence on the nervous system and thereby to the local metabolism have toxins and products of decomposition. Very painful processes are localized in the external genitals, the eve of the vagina and the urethra, as these areas are richly supplied with sensitive nerves. Very strong pains are in the transition of inflammation in the pelvic peritoneum. Strengthening pain may depend on a number of points (voltage abdomen, constipation, coitus).
