I have had lesions for over two years. I would have accepted that they are my imagination until a dentist would not clean my teeth as he said te same lesions were inside my mouth. After the skin breaks and lesions start to heal, crusty brown and black specks can be wiped away I am very diligent in my hygeine habits and cannot figure out what this is. The infest moves from one leg to the other than one arm to the other then onto my back, etc. Sometimes I will not have any problem for a few weeks but it always returns. In places where it has not returned, the skin has been discolored in large patches going from one side of my back to another. Can you help me?
