My left side of my chin and my lip has pins and needles feeling for the last three weeks.  Yesterday at work the pins and needles feeling traveled up my jaw into my ear.  My top of my head felt hot too.  Almost like a burning sensation.  I did not know what to do and I am an RN.  The numbness in my jaw went away in an hour but I still havae it in my lip and chin on the left side of my face.
