I am 41 years old in good health besides being overweight. For the past 4 or 5 days I have been having pain from my chin down thru my colar bone..and sometimes down my arm a little. It comes and goes. And the pain is very minor. I can't tell if it's just neck or what..My neck is sore if I try to bend it.. I also occasionally feel some pain in my chest on the left side..it's very minor also.. Also, I sit at a computer all day for work..so I sometimes get a stiff neck fromt hat...Am I paranoid or is this signs of a heart attack?? It does not run in my my family..
