About 5 days ago, I swallowed a pill that did not go down properly. It felt like the pill was lodged in my esophagus, near my breast bone. Since then, it has been painful to sallow. It has been so painful that I am only eating about 1/4 of what I normally do. It still feels like there is something lodged inside of my body by my breast bone (this causes a stinging pain all the time). I also have had what feels like indigestion in the morning and when I burp, but Maalox brings no relief. Lastly, about 3 days ago, my mid back started hurting out of nowhere, and has not stopped hurting. What should I do? Is this something I need to see a doctor about?
