Suggest Treatment For Cervical Erosion With Vaginal Discharge

Hi, I have been suffering with Cervical Erosion for almost 2 years. I had treatment nearly 3 months ago to freeze the cells. This was unsuccessful, as I continue to have worsening vaginal discharge. I have heard of surgery to scrape away the affected cells and is 100% successful and permanant. Please help as it is starting to effect my everyday life. Thanks
