I began walking on tredmill a few weeks ago. the last couple of times that walked i have had some chest pains. currently i have a uncomfortable feeling in my chest, left arm and left leg. like they are asleep or like i slept on that side which i dont. I feel ok otherwise. mild headache and some neck discomfort as well. i have made an appointment with local heart clinic for this firday. is this something that can wait til then?
