For the last 2-4 weeks (2-3 weeks after I had a one night stand encounter with a girl - first week after, I felt some urethra tingling), I've started to experience lower abdominal dull pain (1.5 inch below the belly line to the right or left), tenderness, also feeling of bloatedness and like something is protruding under the skin (no visible bump) from either the right or the left side (on the left side it also seems to also radiate to the groin or left testicle area) that seems to get activated when I do certain physical movements, like like playing table tennis/billiard, sitting on the couch with my back aligned with the back of the couch, bending over, lifting some bag of groceries, moving my stomach to a certain range that would activate it.
So far I've seen a family doctor, general surgeon, urologist and gastroenterologist. I got blood work, urine test, occult blood in stool test, ultrasound of the scrotum, abdominal complete, abdominal of the pelvis, abdominal wall. Full STDS panel (couple of times). And all came back negative and no evidence for hernia (also doctors did a physical examination for a hernia).
Gastroenterologist mentioned it could be Irritable Bowel Syndrome made worst by stress, but I don't really feel more stressed than usual, also there are no other typical symptoms to IBS such as diarrhea, nausea or anything else. Or he said it could be a stomach muscle strains, but I doubt it can that be felt like it's from the inside of the stomach and radiates to the groin area.
I'm considering to get a CT of the abdominal and pelvis with contrast, with hopes that it will show something that ultrasound doesn't (hernia or something else?), and a stool test for ova and eggs (although I don't have any diarrhea).
I just want to get this thing diagnosed and treated asap, and I feel like so far all these doctors I've seen and tests I've done are completely useless to help with my condition.
Does anyone have any idea or suggestion what could cause the symptoms I'm describing or what other doctors/tests I should see/get?
