Dear cajungal: Your initial sentence of the first post could have been written by an MD! You are so correct. The second most common cause for pelvic pain (GYN is first) is GI issues. The most common culprit for GI caused pelvic pain is irritable bowel syndrome.
In your specific case, the deep lower abdominal pain might be either GYN or GI in nature, so it may take an evaluation from a GYN first--followed by a GI specialist if needed. Here are some possible, GYN sources of the type you have described:
1.? Endometriosis (bits of uterine lining tissue growing on the bowel, bladder, ovaries, etc). The endometriosis implants go through the same cycle as uterine lining—they slough off and bleed monthly. Because there is no outflow for the bleeding, the body creates bands of filmy scar tissue ("adhesions") as a response to the inflammation of monthly bleeding into the abdomen. These adhesions can "glue" together organs in the abdomen.
2.? Adhesions can also be formed if a woman has had an abdominal surgery or a serious abdominal infection (eg PID or ruptured appendix).
3.? Adenomyosis is endometriosis that has grown into the muscular walls of the uterus. In addition to pain it can produce a uterus that is enlarged, tender, and boggy. Unfortunately, adenomyosis is usually diagnosed only after hysterectomy has been performed. One could have a suspicion for adenomyosis if the woman, or her family, has a history of endometriosis.
4.? Pelvic congestion syndrome is also more difficult condition to diagnosis. It involves varicose veins of the uterus or ovaries.
5.? Uterine prolapse can create a dragging, heavy pain. The supportive tissues become relaxed and the uterus drops down into the vaginal canal.
6.? Large uterine or ovarian masses. Even benign masses such as large external uterine fibroids, or large dermoid cysts, can put pressure on surrounding organs.
To get the most accurate diagnosis you would likely need a thorough pelvic exam and an ultrasound. A GYN can also evaluate if elevated male hormones (eg PCOS) are the cause of the unwanted hair growth growth.
As for the sudden, searing anal pain I don't have the expertise of even make a good guess (?spasm, ?neurological). You can ask a GYN, but they may refer you to a GI MD for a diagnosis.
Yours,
Jane
