The OP wrote > my face starts feeling cold, including teeth and hard palate. So I measured and it was 33 c°, told a few doctors and got no response I read that as they measured the temperature of their face. Then, 33°C isn’t outside normal range. https://en.wikipedia.org/wiki/Skin_temperature https://en.wikipedia.org/wiki/Skin_temperature: “Normal human skin temperature on the trunk of the body varies between 33.5 and 36.9 °C (92.3 and 98.4 °F), though the skin's temperature is lower over protruding parts, like the nose, and higher over muscles and active organs.” That page also says “Recording skin temperature presents extensive difficulties”, so that 33°C may not be very accurate.
