Tell her not to worry. I had a cone biopsy at age 27 or 28 and afterwards, once it had healed for about a year, my regular doctor said that if he hadn't known I had had it done, he wouldn't be able to tell. A few years ago I had a recurrance (HPV here too) and had the LEEP procedure done. They knock you out for it but I was pretty alert and felt fine after. Yes, you're sore for a few days but it wasn't that bad. The cone biopsy was much worse to recover from. The worst part for me honestly was..
GROSS ALERT!!!!!!!! (specific details to follow...don't read if you don't want to know! LOL)
the smell. (although the smell after the cone biopsy was really narly too....worse than the LEEP) Basically what the LEEP is, is a super hot wire loop. They use this to scrap and cauterize. So in the end....you have a burnt cervix. It's not that painful afterwards (some pain but more of an uncomfortable pinchy/crampy kind of feeling) and they give you medications in case you need them. I think I took them religiously the first day or two and then not too much after that. I don't remember exactly but I'm thinking I had to wear a pad for a few days at least.....maybe a week or so. Like I said, the smell was....different but again, the cone was much worse.
If she has any questions tell her she's more than welcome to PM me and I'll answer any I can. It's honestly not that bad.
