you're talking opposite ends there friend. I don't think you want the same hands messing around with both places.
As for the colonoscopy... this was my third... get one about every 5 years or so... standard procedure when you're over 50. The colonoscopy itself is nothing... they say you're not 'out' but if not then i don't know the difference because I have no memory whatsoever of going to sleep, or deep relaxation as they call it, or the colonoscopy itself. I'm lying there, they say "We're going to inject the medicine now", and the next thing I'm aware of is I'm sitting in a chair and they're saying I can go put my clothes back on. Getting your teeth cleaned is 100 times worse.
However.. the 'prep' for a colonoscopy... and this is subjective, is horrible. Plan on one miserable day and night, (before the procedure). - JamesJM
