I've been having left sided abdominal pain for months. Originally it was more severe on my left middle side, where my colon is, but recently my whole upper left quadrant has been hurting. I did an abdominal ultrasound last month and nothing was found and have a colonoscopy scheduled in for a month from now.
Last night, I noticed a small lump (hard, maybe 2cm in diameter) right below my left rib (where the bone ends and the rest of the abdomen starts). It's not visible and doesn't hurt to touch, but again, that general area has been hurting. What could this be?
I think that's my transverse colon (from anatomy pictures) but maybe my spleen or stomach? I've asked my doctor for a ct scan while we wait for the colonoscopy but I'm just getting increasingly worried
