He has to stay in airconditioning . Exposure to heat of any source causes his condition to become extreme and unbearable and even whenin 60 degrees a/c room his ears will still sometimes get extremely hot and swollen. Also this condition alternates with out explanation from one ear to the other , or both . is there anybody that knows what this is? His doctors have not be able to figure it out. even after many many tests of blood urine scans . please help me
