For a long time, 20+ years, I have had itching mainly left foot, left hand and left cheek but in the last couple of years it has spread over most of my head. Still left cheek side but above the ears, top and neck. I have on numerous times over the years been to the doctors only to be given creams that don't work or told to stop scratching. I would not scratch if it did not itch (chicken and egg/egg and chicken syndrome?). I sometimes do this in my sleep as there will be blood spots on the pillow next morning or it will wake me up. It drives me crazy, and my wife too washing the pillows, but nothing seems to stop the itching. My hair is short to non at all so there is nothing hidden in it. Any thoughts/ideas anyone?
