I have CAD and just had a stent placed and angioplasty in august, however, my throat has been tightening as if i m having an allergic reaction. When I eat even a small meal, I feel bloated for hours. My bowel movements have not been regular. It doesn t feel like an acid reflux issue. It feels more like the muscles in my throat are tightening up. It is getting progessively worse. I also have a herniated disk between C4-C5 vertebrae. Can this maybe have something to do with it?
