Suggest Treatment For Stinging In Vagina After Applying Veet

I used veet for my bikini line and it accidently got in my vagina. It stinged so much and when i tried to have sex 3days later the pain was too much i couldnt take it and had to stop. A week later it seemed to have healed so i had sex.. the sex was a bit rough so wen i finish my vagina started stinging really bad. The pain is a bit better now but i can still feel it. Is there anyfing i can use to make it better please?
