Thanks for your question on Healthcare Magic.
I can understand your concern.
In my opinion, we should rule out esophageal obstructive lesion and worsening of
hiatus hernia in your case.
Your symptoms like
chest pain, pressure, not able to swallow food down, food stuck midway etc are suggestive of obstruction in food pipe more.
This can be due to mass lesion or worsening of hiatus hernia.
So get done CT thorax and upper GI (gastrointestinal) scopy for the diagnosis.
You may need surgical correction of hiatus hernia.
Don't worry, with appropriate treatment, you will be alright.
So first diagnose yourself and then start proper treatment.
Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
