What Causes Painful Sores In The Vagina?

Hi, my friend sent me a photo and I m concerned for her as she is concerned herself I am not a obgyn and she is African American and her lady part (vulva and outer wall not inner still pink) has a fee sores that s white in the middle like they popped? And she had a weird grey discoloration but it turned out to be dead skin she said cause it peeled right off. Idk if she has herpers or just a infection I pray it s an infection that can be cured... Also she says when she walks it hurts and when she pees it Burns cause the stream is hitting the open wound bumps.
