Hello ? I had erosion during my pregnancy before getting pregnant. Now I want to put in a coil. I asked my gynecologist if erosion can be put in a coil. She looked at my erosion and said it needs to be cauterized. People around me say and say that this is insanely painful, even more painful than childbirth. Cauterizing an erosion. Please tell me if anyone has had such experience or knows anything about it.
