Hello,
Apart from surgical removal of the scar tissue, a laser treatment can be used to vaporize the scarring. This can be tried before surgical removal of the scar tissue. It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
Most gynecologists do surgery, and the gynecologist could answer all these questions.
There are special medical dilators that might help.
