question: For the last 2 weeks or more I have been feeling a knot in my chest. When I eat a meal, I am hungary, but the so-called knot is hard to swollow past. Even when I drink a liquid hot or cold it is the same feeling. I have tried taking pepto bismol, gas x and tums but to no avail. There is a mild concern, since I do have some cardiac issues in my family hx.
