Brief Answer:
not likely due to age and nature of discomfort

Detailed Answer:
HI, thanks for using healthcare magic

It is understandable to be concerned about any pain in the chest area but it is not likely a heart attack.

(A)Age is one of the risk factors (factors that affect the chances of having a condition).
At your age, the chance of a heart attack is very very very low unless you already have a history of heart disease.

(B) A heart attack does not normally present with a history of belching or stomach burns
This would occur with the GERD that you mentioned

Chest pain from a heart attack is typically- central though can go to the left arm of the chest, tight or heavy, persistent.
There is associated shortness of breath, palpitations, excess sweating, dizziness, clammy
Shortness of breath/palpitations can sometimes occur in anxiety as well. Anxiety can also cause chest pain

Sharp pain under the left collarbone is not a description that would normally be seen.
This may be muscular or if it is very intermittent (lasting a few seconds or minutes), may be due to neuralgia (nerve related pain)

If you are still concerned about a heart attack though it is very unlikely, you should see your doctor for an ECG and blood tests

I hope this helps,feel free to ask any other questions

Brief Answer:
a heart attack would not survive a month

Detailed Answer:
HI

A heart attack occurs because there is a complete blockage of blood flow to a part of the heart.

The fact that the symptoms are occurring daily for a month is another reason that it is not likely a heart attack
If parts of your heart were completely blocked off for a month, you would likely be in a very bad way, in hospital

Using medications for the reflux along with diet changes would help the GERD

Please feel free to ask anything else
