Sudden onset of asymmetrical flushing on left sign of face with increased sweating. Seems to be exercise induced following walk/run but also flairs up when working in yard on hot day. Right side of face remains normal color and does not sweat.
Initial internist exam/tests are normal other than long time misalignment in c-spine vertebrae. Soon to have MRI of c-spine and upper t-spine vertebrae.
My personal online research took me to Harlequin Syndrome but no blog poster provided doctor or medical research facility information where they had been screened/treated.
I'm looking for a doctor with some experience or at least knowledge of symptoms and possible causes to investigate and eliminate before deciding it is a benign condition I have to live with. Neurologist? Orthopedic? Vascular? Location is not important.
