dear doctor , i am Owais, age 24, my ear lobe(bottom part of the ear) started turning grey couple of months back, and then it started turning blackish/purplish(left ear) and then the lobe of the right ear also started turning purplish black(but did not spread). the left ear has almost changed its color, and the guys at the salon said its spreading on my face(when i go for a shave). today a lot of people including me noticed that my cheeks are redish, they are not spots but some sort of patterns. i hav also started to feel itchy on my forehead... should i be worried? i saw a doctor couple of months back and he prescribed \
