I am a 26 year-old male. Almost a month ago, I experienced numbness starting in my right thumb and index finger, and it spread up my forearm, upper arm, around the back of my neck, into my left jaw, left chin, left ear, left cheek, and into my tongue. I also felt numbness in my left mid-back, left shoulder blade, left breast, and the back of my left upper arm. This all happened after I had been seated for more than 5 hours. I have residual abnormal sensation in my left chin and lower jaw, as well as sometimes in my left mid-back, left upper arm, and right thumb and index finger. Numbness has come and gone in my tongue as well. My neurologist tentatively diagnosed me with atypical migraine, but I do not think residual numbness is characteristic of this. I really appreciate any input! Thanks.
