Well, sure, you could have the flu, or IBS, or something going on with your colon or bowel.
The only reason I suggested that you could have an infection in your prostate is because you both were treated for her PID. Did they ever find out what caused her PID? Did they test her for stds?

Besides that anything else?
If you have an infection in your prostate, it can cause bowel pain. If you haven't seen a doctor about all this, you should.
