For a while I have been having a sensation that I can only identify as "shaky nose". My nose bones start feeling tingly and so does my upper chest. My face feels very red and hot. This happens off and on (usually every other minute) until it makes all my face and chest feel shaky, and then everything is back to normal. It used to happen frequently before, but after a few instances, it's now back. The sensation also sometimes happens when I think of a memory related to having the sensation.
