Erosion and acetowhite changes

Hello, I'm new to the forum but not sure where to turn.  I visited my doctor as I need lots of psin in lower side and spread to back.  Along with bleeding after sex.  Doctor refered me to hospital in which I had a smear, the two biopsies.    Letter to my doctor received yesterday said I had a large erosion with acetowhite changes,  I have No idea what this means.   I'm still waiting for biopsy and smear results.  Thanks everyone
