Is it bad?

Hey guys. So I have a yeast infection and I'm trying to treat it naturally using home remedies. I tried doing the tampon soaked in coconut oil. I tried putting the tampon in but my vagina was way to sore. It just felt uncomfortable being up there. I was wondering if this is normal? I've already tried taking a warm regular bath, I've taken a bath with apple cider vinegar, and I just put some yogurt around my vagina. If none of these work should I try taking over the counter medicine or should I go see my doctor? Also it's so itchy and sore that I can barely walk or touch it without it being sore. It's really annoying and I just want it to go away😩😭
