Have commented before and still the same... stared June 2022 on and off burning face mainly cheeks but then neck etc., sometimes red sometimes pink and sometimes my normal pale face but burning hot yes as if on fire. No tests done on me. Dermatologist said not his field. Neurologist said not his field. Guess I am all alone in a field. Over a year and now mainly at night as right now 8pm, last several hours. Creams etc. Were suggested as a trial basis but its not skin so why cream. I was putting small cold pads on face during night. But kept falling off but helped. Now I just go with the flow and put up with it but quite painful. I started taking selfies but no one seemed interested. I started a binder about he different things it could be but again, no one wants to look at it. Best of luck to you, hope find out what it is.
