For the last two years or so I've had a this problem. It started as an aching pain in my lower left abdomen, about two inches down and three inches left of my belly button.
The pain has come and gone many times over the last couple years and each time, the duration and severity of each instance has increased. At first it was just a couple days at a time. That moved on to weeks, then months, and now it's always there.
A few times it has been accompanied by swollen lymph nodes to the left or right of my groin. These returned to normal after a couple weeks.
About a week ago, the pain got a lot worse, and spread across my entire lower abdomen, and down to my pubic bone. It increases in severity throughout each day, and sometimes the location moves around.
In addition, I've started having fainting spells and am now worried about driving because I often feel like I'm going to pass out.
I've been to six doctors for this and none of them can figure it out.
I know it's not an infection because I've tested normal for white blood cell count.
I know it's not colitis or diverticulitis because I've had a CT scan with a normal reading, and a colonoscopy with "healthy" results.
I don't have any bleeding or diarrhea symptoms.
I've gone one a wheat fast to see if it's Celiac. I've skipped alcohol to see if it's related. No change for either.
I'm 29, male.
edit: I'm not on any meds.
