I have sores in my vagina, on my butthole and back of tongue/ in my throat. I dont know what they are. They look like blisters or ulcers.

STD screen . Sorry you are not feeling well. You need a full history and physical exam in urgent care. Get a full urine and blood sexually transmitted disease screening. May or may not be Herpes. Get partner tested treated ASAP as well. Go to ER if urgent care not available. Good luck. .
