I had a sore on the bottom of my "lip" Dr said that it was not an STD but that the tissue had split clean and it just felt like a raised sore because of the cut skin. It has been like this for months getting deeper and it hurts. He gave me Estrace Cream and said to come back in 2 wk's if it does not go away.. I have not been able to find any info that says Estrace is good to heal cut skin?
