doctor told me to grow a bush.

Doctor checked me down there as I thought I had a yeast infection/thrush
And she said there no sign of infection.
And asked if I shaved I said yes she said as it looks to me like you have a shaving rash.
But it's itchy where there's no pubes growing... its itchy inside on the sides (labia minora) 
Is this a shaving rash as there no hair there? She didn't give me anything to help it. What do you recommend ?
