...a gyn surgery? If so I have had it and been a nurse present while it was done. It is a freezing that is done to the cervix and depending on the doctor only freezes for about 3 minutes....but it seems forever while it is being done. Really there are very few nerve endings in the cervix so....very minimal discomfort. Then the cells are sloughed off slowly while the body regenerates new ones.
Of course there could be other types of cryosurgery and I cannot tell you are a male or female
Hope this was helpful!
