Skin around Vagina burns. Help?!?

I had sex on Saturday and the condoms were pulling in my skin a lot. I got diagnosed with a yeast infection today and took the medication (pill) a couple of hours ago. I know it’s gonna take a while to kick in but the sling around my vagina opening burns so bad and it feels like it’s been ripped open. Any tips to help it heal or feel less painful? A girl need help
