Suggest Treatment For Burning Sensation In Vagina Leading To Painful Intercourse

Hi,

I am 27 years old female, 5' 4" in height and weigh 108 pounds.
Problem - These days my vagina burns when penis is inserted into it and we are not able to sex for the same reason.

History - Had a miss carriage (miss carriage happened at 5th week) end of march'11 and since then this new problem has started.

Around Jan'11 got yeast infection (which I diagnosed at home with the testers available at pharmacy and used an ointment available at store)

Please help me in getting a solution to my problem.
