what is this???

Went to a dr because I had 3 little red dots on my inner upper thigh and one swelled up. They gave me a steroid shot and in two days it was gone. Just woke up to this and sticky white discharge today! What is this??? It's itchy and uncomfortable! Any help would be appreciated. 
(Picture is of inner thigh very close to my vagina and there's a few on my butt and some on my upper groin area!
