The last couple of weeks I noticed a serious flareup though. I did notice that the side of my abdomen was particulary sensitive when performing self-massage with a rubber massage ball, causing referred pain in the rectum. I was already thinking it had something to do with my bowels but my PT was able to pinpoint the exact location today. After going over 2 other possible trigger points in the abdomen the 3rd one was spot on. He pressed down and told me to lift my leg which caused massive pain where he was pressing. He told me it was a trigger point in the external abdominal oblique.
Apparantly it can cause referred pain in the rectum and testicles, which seems to the case with a lot of abdominal trigger points.
This picture gives a good idea of its location.

He subsequently treated it and advised to refrain from exercising my lateral abs for a while.
I'm going to take it easy for a couple of days and see where this is going.
He will treat the other side in 2 weeks or so.
