My nose has been tingling at least 5 to 6 times a day for about 2 months now. It feels like it does when you go outside when it's cold and you go out too fast and your nose gets tingly and your eyes water. Mine will tingle with no prompts though. It tingles when I drink or when I eat, walk, sitting still, etc. It doesn't usually make my eyes water and it really can be painful. It is getting way annoying! I don't have a cold, no runny nose or coughing, etc and no other symptoms. Sometimes I'll get a little bit of a headache, but not always. Has anyone else ever experienced this or am I crazy?
