Last Dec. all of the sudden I felt one side of my face start burning..like it was on fire. This happened sometimes for minutes..sometimes for hours...it has been going on...off and on...since then. I can always feel a difference in one side of my face and the the other. This also has happened to the front of my thigh..same side...shoulder and neck. At first there was no redness at all. Then around May my face would get red very easily. So I was diagnosed with Acne rosacea..which is now aggravated by the burning..and the redness is bright, hot and severe. It affects both sides now..i think the Rosacea is what is happening on the other side. WEnt to Neuro, Rheum. with no answers.
