A Few Months Ago I Was Experiencing Heart Burn That

A few months ago I was experiencing heart burn that came and went. I attributed it to a lot of stress and pretty consistent diet of nuts etc, it eventually died down. Presently, I am experiencing intermittent back pain, sometimes what feels like a lump in my throat, shortness of breath and ear pain. With shortness of breath, I am able to catch my breath but I definetly notice it.
