Can't find anything online.
Got GP consultation this morning and he can't help as my phone won't support the app they use, so I can't send over a picture 
He has however said he will see me if it hasn't gone in 4 weeks.
Just looks awful really. Basically he has olive skin and they're like little raised white dots on his hips, under his arms and a bit on his back.
Thanks so much if anyone could give some answers as I've not seen anything like it before (use to be a nurse)
