Suggest Remedy For Severe Vaginal Pain

I have been experiencing vaginal soreness and pain for three months now. I do not have any out of the ordinary sores, vaginal discharge or other symptoms. I had a severe UTI four months ago and ever since I have experienced severe pain in my vaginal entrance that gets worse when sitting. I don t like to self diagnose but I have been to my doctor who prescribed me a steroid cream that did nothing for me, after that I discovered online that all of my symptoms match up to Vulvodynia. As I said I don t like to self diagnose, but I m trying to figure out if there is another possibility. This is beginning to cause excruciating pain even when just trying to sit in a chair. Please help!
