let me start off by saying i am a 19 year old girl, 5'7 about 135-140 pounds (it varies).
sometimes i get very VERY painful cramps in my lower abdomen area.. it gets so bad that i cant stand, sit, lay or anything.. it makes me pretty much freeze, bent over because its so painful to move.. this has been happening for years.. at random times.
i have no idea if this will relate but a few weeks ago, maybe a month and a half ago, i started getting blood in my stools.. a few times when i wipe there is bright red blood. Also, there is some blood on my stools in the toilet.. keep in mind that i dont ALWAYS have blood in my stools.. but most of the time.
Today, i went to the bathroom and i wiped and there wasnt any blood but there was like a white substance.. fluffy kind of white substance.. about penny-sized.. and i looked and there was some on the stool as well.
I dont have to go "#2" alot.. ever.. i maybe do it twice a week. And i also find that i am VERY bloated all the time.. most of the time i look pregnant

.. i cant help it, but my belly pushes itself out all the time and its especially worse right after i eat.
also, no idea if this has anything to do with it, but i have had swollen lymph nodes in my neck for about a year and a half.. the doctors wont do anything about that. and for a couple months i've had lower back pain (i sit alot?).. and the doctor just told me to do these stretches..
what could be wrong with me?!
