Weird feeling after period

So my period just ended and I’m having a weird symptom. The inside of my vagina feels dry and sore.. a burning feeling. My labia is also burning. I’ve never had this before. It started immediately when my period ended. It almost feels like when you take a dry tampon out, it’s a very sore feeling. It’s hard to explain. I’ve never had this happen before and I’m 21. Does anyone know what this could be?
