I am 62 year old, with diabetes (52yrs), MS, acid reflux, hiatal hernia and more. I have been having this feeling like I could vomit on and off since Wed. I had a lot of anxiety this week with projects in the house, etc. Today, I just ate a sandwich and my chest feels tight. I also am short of breath, poss allergies but I did clean out a refrigerator on Saturday at my dad s house that had some moldy food. I am able to do things. It just always feels like there is something stuck in my throat and if I vomited it would feel better. The chest tightness has diminished now.
