呢個網友形容既同我感覺好似: "I usually experience sharp aches in my anus when I'm menstruating, that last for a couple of seconds at a time. Occasionally they're so bad that if I get one while walking I have to stop and hold onto something for a while until it goes away. The pain feels as though it continues a little bit into my rectum, as well as the sphincter."
i am suffering from the same case for about ten years, it is called endometriosis...the doctor said the only thing i can do is taking a medicine to release the pain or do the operations.....
