I feel a small pinch in my chest from time to time that only lasts for a second, the left side of neck hurts if I bend my head a certain way, and sometimes my arm pit
aches, but nothing really painful. I have not experienced any shortness of breath, coughing or any kind of mucus coming up. I do ccasionally have heartburn and feel a little nauseated, should I be worried that this is lung cancer?
