I have a very strong burning sensation periodically, but often that starts at my throat, and quickly radiates to my chest, and a great part of my back. Have taken TUMS, and acid reflux tiny over the counter pills, have gargled with Peroxide, and nothing helps. I am 77, and in very good health. Are you charging me for giving me advice? Tomorrow I am making an appointment with my geriatric doctor at UCLA to get to the bottom of this.
