i had one removed a year ago. it had changed over quite a short time but turned out to be benign.
when i had it chopped off (the usual treatment), i didn't even need a single pain killer afterwards, it's the smallest, safest operation in the book; my family doctor did it with a tiny injection of local anaesthetic.
it was so pain free, i had to look to make sure she was actually doing it!
(sorry for being gross)
so see your doctor before the end of the month and your priest too, but having these (and worrying about them!) is surprisingly common.
may God give u peace.
