I do not know if you ever received an answer to this question, but I have the same issue. I was diagnosed with endometriosis and had surgery to remover adhesions. My cervix still "looks angry" according to my gyno, she kept thinking I had an infection, she literally tested me for everything including cervical cancer. It was none of those things, basically the interior wall of your cervix just extends onto the outer portion, and since it is much more sensitive, you bleed easily and can become sore. It doesn't go away, at least mine hasn't.
Are you still dealing with this, please give any updates you may have.
