My Question Is For My Daughter. She Has A Rash

My question is for my daughter. She has a rash on random parts of her body. It is very itchy and when she itches it spreads. has been to her doctor and they said she may have gotten into something outside due to her new job consisting of landscaping replanting shrubbery and flowers. She also has a lot of yeast in her vagina and the rash on the outside. She has tested negative for hpv, but her doctor is referring her to a gynochologist. was just wondering as a parent if you could give me more insight on this.
