I have a condition called Alopecia Areta Plano Plarus. I've had it for over 8+ years. I can't understand why the pigmentation of my skin is affected on my face and neck. Nothing clears it up. I've be going to a dermatologist during this period. Can you give me some insight? Could it be I have discord lupus?
