I saw dermatologist and neurologist, both said not in their field. No rheumatologist in our area. Been a year with no diagnosis. I made jump a 3 ring binder with 8 possible causes... but no one interested in it. Mainly face then down neck etc and sometimes arms and legs would use up lots of cream and then careful on face as might get in eyes and have glaucoma etc etc ... and so it goes on. Five hours at a time and now heat, stress and ?? Seem to start it the burning is often red face but not always, I am a jigsaw with many pieces missing!
