Colonoscope, tooth extracted, brain surgery, in last 3 years. Major surgery they do the catheter thing. Brain surgery: they took the cath out too early, as far as I was concerned. The surgery gave me full-blown incontinence, they put diapers on me (badly, and they were lousy ones). Went home that way, after 3+ weeks. It has faded slowly.
Latest tooth extraction was by oral surgeon instead of previously by dentist. He did have to put in 3 stitches. It was really quick - unlike 2 impacted wisdom teeth back when I was in college. Whatever this oral surgeon used instead of novacain, no problem, didn't put me out, no big deal, none of that "feels swollen" afterwords. No problem, afterwards, except near-liquid diet got boooring.
Don't sweat it, indeed.
cheers!
