Thanks for writing in.
It is unlikely that the burning sensation you have is due to any of the other problems you have ( like fibroids). Neither is it due to the Ovral
that you are having.
It can be due to an infection where there would be a foul smelling discharge as well. In addition, it can also be due to excessive douching and washing with harsh soaps.
So I would suggest you see your gynaecologist and totally avoid using any chemicals or soaps to wash the vagina. Use only lukewarm water to clean the area.
Hope this helps
