I jog several times a week. Recently, when I have jogged a mile or so, the right side of my forehead & temple begin to tingle and get numb. Sometimes this goes into my cheek as well. Last night after I finished my 3 miles, my ring and middle fingers lost color and got very cold. Are these just symptoms of exertion or should I be concerned and consult a physician? Any thoughts and/or suggestions are appreciated.
