I went to the GP about 2 years ago as I had a patch of discoloation. The area was white with no pigment
I have dark olive skin
It's now spread to my hands and I'm pretty sure it is Virtiligo
I went back and he said 'Do you fake tan? That does go patchy'
I am interested to see if it looks like fake tan? 
I tried explaining that no, that's my skin colour. The white patches are the discolouration but he didn't seem to believe me and sent me away with an emollient hand wash...
Want to go back but just wondered what people thought
