Itchy vagina?

I’m not sure if I got the write place to post this but for the past couple days at first it would hurt when I would pee feels like a needle is getting put in every time and now the pain is gone and the inside of my vagina is constantly itchy (like the inside where the tampon goes) this never happened before and I don’t know if I go to the doctor or just wait it out

There’s no weird discharge or smell and my sti tests came out negative. I’m dying over here I can’t even go back to sleep because of it lol.
