Yes I can relate to your issue of your face becoming red. Also, my left ear becomes red very often. When I was seen by a very famous RSD Dr. he indicated this is typical with RSD and mentioned exactly what it was - but I forgot. My face feels like it is on fire. I often stick my head in the refrigerator. Also, the light really bothers my eyes. Night time driving is a an issue at times. At this time I have no problem with the computer screen.
Sorry you are experiencing these problems.
Best wishes,
Sydney
