I need to ask a delicate question about piles....

[FrayedKnot]

Has anyone ever had a prolapsed pile - I mean the sort that doesn;t go back by itself - and it has resolved using creams / pessaries, or can they only be sorted by having some sort of surgery?

See this classic - DIY pile surgery

No I'd prefer advice from people who have had theirs treated by a medical professional!

I dont blame you.... lol
