Any infection in your vagina can cause foul smell from vagina.
is most common cause. Fungal (yeast) infection can also cause foul smell.
You can apply Candid

The dryness in your mouth & throat seems to be due to oral infection. And this infection has reached up to your ears also.
You will be requiring a 10-15 days course of antibiotic.
