Hi, I have been feeling intense burning sensations (like rubbing of jalepenos) on my face while sleeping at nighttime. It usually begins with cheeks then face, ears, neck and (at times) spreads to arms and feet. Also, arms and feet feel itchy and once you start itching it just doesn t go away. It is more frequently nowadays. Last night, I felt the same burning sensation on face/ears but (not as usual - for the first time) it followed by me feeling nauseated, extremely dizzy and sweating profusely. I am borderline diabetic with Hypertension - taking pills and both are well managed. Your opinion is greatly appreciated!
