Thanks for your question on Health Care Magic.
I can understand your concern.
In my opinion, you are mostly having GERD (
gastroesophageal reflux disease).
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,
chest tightness, pressure etc. Alcohol cause more laxity of the sphincter.
So alcohol makes your symptoms worse.
So quit alcohol as soon as possible.
Avoid stress and tension. Avoid hot and spicy food. Avoid large meals, instead take frequent small meals.
Take
proton pump inhibitors and prokinetic drugs.
You will mostly improve with all these.
No need to worry for heart diseases because you are too young (20 years) for this.
Don't worry, you will be alright.
Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
