Infection of some sort(vaginal)

I bought a new brand of toilet paper about 2 weeks ago and it’s the only thing I can think of that did this... I’ve been burning (down below) SOOOO bad and it feels like I have cuts and stuff down there and just feels so irritated and painful everywhere... it’s pretty red too.. can using a new brand of toilet paper tub me completely raw and have soooo much pain there?
