My daughter has chronic fatigue related to tick born disease which has been under treatment several years. She has developed a very dark tan without being in the sun, and some areas like the front of the neck, above and under the lip, and other skin fold areas are becoming a darker almost blackish color. There is no excess hair growth. She is now getting little white spots scattered all over in the tanned area. Can you give us any idea what is going on and how to treat this? Would you have the name of a doctor that is knowledgable about this so we could get somewhere with diagnosis and treatment please. She has the other symptoms of CFS also. Thank you.
