Pimple on vagina and on period

Jasmine • My name is jasmine I`m a fun and happy girl
So this morning when I woke up and I went to the bathroom and my vagina was hurting and I look down and it's a pimple on it and it hurts so bad and when I put on a pad it hurts even worse but I ran out of tampons. Is there any thing I can use to take the pain from the Pimple away from my vagina it's very painful.
