Talk to your Doctor. She's charging us a good buck for the decade or so of training herself not to show embarrassment. If you're a colon-cancer risk, you can work into it (sorry) from the angle of the colonoscopy you'll be needing and how to get ready for it.
Back in the '90s, mine sent me to a guy at Western Hospital who I didn't much like, so then he booked me with a Doc. at the Rudd Clinic who was great. He moved on and now owns his own place — the Holly St Clinic — but sees no patients himself.
Most of mine were internal. He did them with rubber-band ligatures, basically a tourniquet over the protrusion that starves it of blood so it dies, shrivels and falls off. And out, not that I ever noticed. The procedures took about ten minutes and were only uncomfortable, not painful (although you're aware someone's been busy back there for a couple of hours after). But he did 'em one at a time a week or more apart. The final one was external, a skin tag sorta; that one got me a local anaesthetic, and he used an electro-cautery tool to burn it off and seal the wound. Painless, but it did smell a bit BBQish. That took half an hour or so, and I don't recall any after-effects, but I betcha Tylenol™ was involved.
I recently developed another external one, and my cardio guy strongly recommended a hospital surgery which ruled out Holly St. or Rudd. The guy at East General seemed fine, the procedure was general anaesthetic with Tylenol3™ afterwards for pain control. It was not needed after the second day, but shitting wasn't anything like normal for a solid week (and I use the term solid only about the time involved: The actual product was either too much that or not nearly enough that, in spite of stool softeners, Metamucil™ as prescribed and occasional baby enemas). But everything calmed down, and is now fine, although there is a small post-surgical scar that has been a bit of a surprise to some.
You did ask.
PS: If they treat the ailments of that end of the alimentary, they almost always do colonoscopies as well. The fewer strangers poking the better I say.
