Thanks for your question on Health Care Magic.
I can understand your concern.
You are having left sided
chest pain which is radiating to jaw and arm. This kind of chest pain is commonly seen in heart diseases.
So better to first get done ecg and 2d echo to rule out heart diseases.
If these are normal than no need to worry for cardiac diseases.
You are also having
bloating of stomach.
So possibility of GERD is more.
It is due to laxity of gastroesophageal sphincter.
Because of this the acid of the stomach tends to come up in the
esophagus and cause the symptoms of chest pain, bloating etc.
So avoid stress and tension. Avoid hot and spicy food. Avoid junk food. Avoid hard to chew food.
Start
proton pump inhibitors. Quit
smoking and alcohol if you have these habits.
Don't worry, you will be alright.
Hope I have solved your query.
Wish you good health. Thanks.
