I just been diagnosed with vitiligo, I have it on my penis and neck at the moment. I am 30 years old. Will it spread? Is there a cure? Also due to it being on my penis, it has affected my confidence.

Does anyone here suffer from vitiligo? Are there any cures for it or to stop it spreading? I have noticed a white spot on my neck and also my downstair region has white spot on it. Is this vitiligo? Can I get referred to a dermatologist by my doctor? Is it better to go private and go through someone...
