Quoting RainbowDash:" You can have adhesions and scar tissue internally without there being outward symptoms of it. I did. ... [snip!] ... could have it and it could be bothering you. Any chance you're pregnant? I know for me, my old scar hurt when I got pregnant."
I didn't know that about adhesions, I always figured they would be noticeable at least during my pelvic exam.
As for chances of being pregnant, it would be incredibly low as my sex life is almost nil with the beginning of the hectic holiday season, that and condoms work well when used correctly, which we do.
Not that I would be averse to the idea, I would just be extremely surprised.
