My vagina is hurting and it has small bumps and reddish it doesn't hurt me or itch but when I pee it really hurts what should I do? It could be rashes

Urination/vag pain. What you describe may represent vaginal ulceration caused by viral infection (herpes II). Other kinds of infection (fungal: "yeast") can make the vaginal lining raw and very tender when exposed to urine. See your gyn for an exam and testing.
