Hello Doctor I ve been suffering for 8 years now of a skin allergy that appeared around my whole body expect my face, neck and palms It makes my skin very dry. And when it goes under the sun it turns into white spots It also decreases and increases according to his I feel. For example if I sleep for long times it decreases but never disappears And if I sleep less or I stay awake late at night it increases especially on my arms I ve asked so many doctors but no one could help I wish you could Thank you
