I've begun to experience a strange sensation in my right arm and hand during the past few days, where I would begin to describe the sensation as the arm falling asleep, but it definitely is not the same feeling.
There is no tingling, no burning, and no pain. There is no loss of sensation, when I touch my arm during these episodes everything feels normal to the touch. I think the strange sensation is best described as a cool breeze blowing over the arm (without the sensation of motion). The feeling extends from mid bicep down to my hand, primarily only affecting the bottom half of my hand (middle, ring and pinkie finger as well as the heel of my hand - index finger and thumb seem to be fine).
I haven't noticed this affecting any other part of my body. Anyone have ideas as to what may cause this strange feeling?
