I just had cryosurgery 3 days ago. Is it safe to wear tampons?

Cryosurgery. The reason people are told to keep anything out of the vagina is to allow the cervix to heal and to prevent bleeding during the healing time.
No. Following cryo surgery on the cervix will cause significant discharge as the cervix heals it is best to use and pad for the first week to 10 days to avoid further irritation and allow the remolding of the cervix. The tampon may cuase unnecessary irrtation and healing may be delayed.
