Hi will try and keep short. Since June 2022 burning face, esp, cheeks whether face flushed or not, saw dermatologist Jan. and didnt think his field.. gave some ointment but said was a shot int he dark so I didnt use: waiting til end of April since last June here in Northern Ontario, Canada, to see Neurologist.... I have it now down one side of neck and ear and also have had P.N. in hands and feet for years coping with but now going up my legs and burning shoulders etc. comes on quickly... but started in right cheek and I thought a tooth issue but dentist says no ?? ,but not MS to my knowledge. The facial pain is burning as is the other now and I have wondered if: food; where I had molars out at dentist year or so ago; allergies; nerve endings; any of my few meds I take; stress; off gas from our natural gas furnace???? ... and have changed toothpaste, pillows, don't use laundry detergent just hot water/dryer etc. etc. The pain is quite bad can last up to five hours day or night, and only thing helps a bit are some small cool pads keep in fridge, not freezer: they hurt at first but then bring relief. I can get at any time during day or night and on top of other medical conditions its a bit much to cope with. Hoping Neurologist might know... I think it is nerve pain, I am 79.
