Very Inflamed vagina day after sex

I had a tear from sex that I’ve had for going on 2 weeks this saturday (I had rough sex on the 3rd). Had sex again Tuesday morning and it got PROGRESSIVELY worse when I looked that night. The tear looks very abnormal and seems to have gotten bigger, as well as swelling. It almost looks like hemorrhoids, but on the bottom on my vagina. I know I should’ve waited for the tear to heal, but I thought I’d be ok. It is so swollen down there it is almost to my anus. I’m going to the doctor next Wednesday, but am scared that this may be the result of something incurable. I don’t have any blisters or open sores (other than the tear I previously mentioned from sex). Please tell me something to ease my mind. I’m freaking out. Even if it was an std, it wouldn’t just reveal itself the same day I had sex, right???
