A WEEK AND A 1/2 Ago I Chocked On Food

A WEEK AND A 1/2 ago i chocked on food I was eating;

I couldn't breath, was alone, so i did what was the only thing I could do, I did the Heimlich procedure on myself by throwing my self on my counter top. That dislodged whatever was stuck and i was able to breath again. I went to see my doctor and he told me i bruised my esophagist. since then when i eat i feeling like a need to belch but can't, unless i take baking soda and water, apple cider vinegar, or ginger ale.
do have discomfort around the bottom of my rib cages, which is where I hit the counter top. How long will this discomfort go on?
Thank you for your time.
