Sensitive vulva

Georgia

So up towards the hood of my clit my vulva is very sensitive. I just shaved yesterday, I didn't think I cut myself or anything on that side. It feels like when you're becoming sick and if anything cold touches you your skin gets really sensitive. Idk if it's just shaving or if something is wrong. There's no bumps, no discharge. It was kinda red last night, it looks a little better now. Any suggestions on how to make the sensitivity go away?
