If this problem is going on for the last 10 yrs, it is very unlikely to be something serious. However, it is useful to get a follow-up chest X-ray once again. Sometimes if a part of your stomach herniates through the diaphragm (called hiatus hernia
with acid reflux
), it can give you pain in the area you have mentioned. Better to get an endoscopy
done if you are willing or a barium swallow. Try taking some anti-acid medication from your doctor called proton pump
inhibitor and see if this helps. best wishes.
