Got some tests done... Sounds like I have esophagitis! Been put on a new med to help heal it :)
I'am no Doctor but I would suggest you see your Doctor again and request a chest CT scan to check what comes up. If you feel worse and do not feel improvement or feel heavy, or a noise in breathing or your swallowing gets worse I suggest you go into the ER immediately never assume that your Doctor knows exactly whats wrong with you their humans and once in a while make mistakes its always good to get a Second or even Third opinion. Keep me updated. God Bless You! & may they find whats wrong with you and fix the problem that's causing the problem.
I've got a cold right now and I have been coughing a lot...all that coughing has made my chest sore....I would call the Dr. and ask if you should be concerned...
