Thanks for your question on Health Care Magic.
I can understand your concern.
GERD (
gastroesophageal reflux disease) can cause similar kind of Central
chest pain.
But since your chest pain is associated with exertion (cleaning snow), we should first rule out heart diseases for your chest pain.
So get done ecg and 2d echo first.
If both are normal then no need to worry for heart diseases.
GERD is the likely cause for your symptoms.
So avoid hot and spicy food. Avoid junk food. Avoid large meals, instead take frequent small meals.
Take
proton pump inhibitors and prokinetic drugs.
Don't worry, you will be alright, but first rule out heart diseases.
Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
