Welcome to HCM.
It sounds as though you have injured your diaphragm , your symptoms fit a hernia
and subsequent reflux into the esophagus
. You need to see a surgeon whom can perform a gastroscopy and/or have a barium meal
done. They then need to decide whether surgery is needed or conservative treatment . Please do not delay as there may be long term complications if left untreated.
I trust this helps you.
