I think you are not spelling properly. There is no disease like Reinhold in medical text books. It can be Raynaud's disease or Raynaud's phenomenon. This is a condition which is characterized by the discoloration of fingers and toes after exposure to heat, cold or emotional event. This discoloration is due to an abnormal spasm in the blood vessels which reduces the blood supply to the fingers and toes. This turn the fingers first blue and then red after reopening of the blood vessels. Etiology of this condition is not known. This conditions is managed by avoiding exposure to infection, trauma and cold.
