Thanks for your question on HCM.
Since your ECG and
stress test is normal with controlled blood pressure , I don't think you are having any cardiac cause for your
chest pain.
In your case GERD seems more appropriate cause.
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.
The
gas problem you have, is mostly a part of this only.
So try to follow these steps for better symptomatic relief.
1. Avoid hot and spicy food.
2. Avoid large meals, instead take frequent small meals.
3. Avoid stress and anxiety.
4. Start
proton pump inhibitor.
5. Go for walk after meals.
6. Keep 2 - 3 pillows under head in the bed.
