What the hell...

So when I had my c section two years ago they left a part of the stitches hanging out of my skin ( don't think it was intended). When I went for my follow up my OB just snipped off the access that was visible at that time.  
Anyway, I tend to groom down there so what I thought was a pimple along the line of my scar from a possible ingrown hair may actually be a part of the stitches that never dissolved! Anyone else have something similar happen? I'm just creeped out by it now LOL
