I have been having chest discomfort. What could it be?

Hi, 

Welcome to icliniq.com.

Since you have mentioned that ECG and other tests came out to be normal, it is not associated with any cardiac abnormality.

As you have a history of gastritis confirmed through EGD (Esophagogastroduodenoscopy), there is more possibility of association with acid reflux.

Acid causes irritation of esophagus and leads to inhibition of vagal tone (vagus nerve supply to the heart) resulting in increased heart rate.

This in turn leads to palpitation, chest discomfort, burning sensation etc. 

I advise you to follow these:

• Do not consume spicy food, tea, coffee and alcohol.

• Avoid smoking. 

• Consume water 5-10 minutes after the meal.

• Do not lie down or sit immediately after meals, rather take a small walk inside the room.

• Take capsule Omeprazole + Domperidone once daily on an empty stomach. 

Another possibility is that you could have some muscle spasm/pull if this sensation is pain.

If there is pain during movement of chest then you can take some muscle relaxant like Chlorzoxazone in combination with some pain killer.

The word chest discomfort indicates that it could be palpitation (feeling of one's own heart beat which usually occurs when the heart rate increases), tightness in the chest, burning sensation or chest pain.

If the discomfort persists, revert back with details like dietary habits, blood pressure and medical reports to a cardiologist online --> https://www.icliniq.com/ask-a-doctor-online/cardiologist
