I have two types of pain, and I m not sure if one is related to the other or not, if they are a gastro- intestinal problem or a GYN problem. The first I will discuss is the lower abdominal pain . Located in the center of my abdomen, right in the pelvic region, deep, not superficial. It s not even a pain really, more like an uncomfortable pressure. It never ceases, but at times its barely noticeable, and at other times, it s painful, but not sharp pain at all, but dull heavy almost-pain but isn t. Easy to endure, easy to ignore. Coughing and sneezing cause painful pressure. Sex is often painful somewhere deep inside, near my uterus. Almost never get constipation, usually have loose bowels and alot of painful gas... I have regular periods, which are medium / heavy flow with alot of cramping and passing blood clots, sometimes as big as dimes. My cycles have always been regular, except 2 years ago. I was also 140 lbs overweight (topped the scales at 270 lbs. on home scale), I was working and going to school full time. My periods stopped for about 6 months. Later, when I back on a normal schedule, and lost some weight, periods went back to normal. I have since lost 70 lbs. I also believe myself to have a hormone imbalance of some sort, cause I grow facial hair (lip and chin , male pattern hair growth), and quite a lot of body hair as well. I have to shave facial hair daily. I don t know if this info has any relevance here, but I thought I d throw it in anyway... Now for the rectal pain. It comes about once every few months. The only way I can describe it is like this : it s like having a lightning bolt shoved straight up my butt! A bolt of white hot electricity shooting straight through my rectum... It is so painful, so intense, it has literally knocked me of my feet, I was walking and I fell on the floor in pain. It hit me while I was driving once, and I remember lifting my whole behind off the seat and arching my back, and my foot stomped down on the excellerator and I couldn t move my leg to stop. I can usually feel this pain about to happen, it gives a warning, and I have to brace myself before it happens, or else I will fall. It s what I would imagine it feels like to be electricuted. These intense pains last about 10 - 20 seconds, and then they re gone for months, like they never existed, forgotten about until months down the line when hit again.
