Over the past two weeks I have had a feeling of bubbles in the back of my throat that come and go. I notice it more now after eating. It feels like I still have something in my throat right behind where I swallow. It goes away and then comes back even if I am not eating anything. Today I am getting that along with a burning sensation on the right side of my chest, like by my lung. I can breathe deep without pain. I am 55 years old, male, and have 5 heart stents. I take RX medications - Plavix, Protonix, Isosorbide, 81mg aspirin, and Losartan. I also take CoQ10, Potassium supplement in the morning and magnesium at night with the Losartan. I will occasionally take Zantac for acid before going to bed.
