I am a 40 year old female and I am 5'7" tall and weigh 125 lbs. I have recently started a high intensity workout with a trainer and during my workout yesterday I got done doing a pretty intese run on the treadmill and when I got off and sat down, I felt a strange tingling or numbing sensation on my face. it started on my nose and then reminated to my mouth and chin area. It kind of felt like it does when your foot falls asleep, not the needle pain but the first numbing. Should I be concerned?
