Scarring

I have just been to the Colposcopy clinic as I have CIN3 and the consultant wanted to do the Lletz procedure there and then but I have refused as need it under general as first one was very painful.

He did agree and when he did examination said my cervix was very scarred from first Lletz and that after the 2nd I would have to go to Colposcopy clinic for all future smears?

Has anyone else had this?
