Chest pain can be confusing and frightening, especially when it is unclear whether it is caused by gas or something more serious like a heart problem.
Gas-related pain may sometimes change with body position, burping, or passing gas. Heart-related pain, on the other hand, is more commonly felt as a heavy pressure or tightness in the chest and may spread to the left arm, jaw, neck, or back.
These differences can offer helpful clues, but they cannot confirm the cause on their own. Because heart attacks can sometimes present in unusual ways, any persistent, heavy, or unexplained chest pain should be treated as a medical emergency until evaluated by a doctor.
1. The "Type" of Pain: Sharp vs. Heavy
How you describe the pain is the biggest clue for doctors.
Gas Pain: Usually feels sharp, stabbing, or cramp-like. You might feel a "knot" in your stomach or rib cage. It often comes in wavesit hurts for a minute, stops, and hurts again.
Heart Attack: commonly feels "sharp." Most survivors describe it as pressure, squeezing, or heaviness. It feels like a tight band around your chest. The pain is constant and usually lasts more than a few minutes.
Important Note: If the pain gets worse when you press on your stomach, it is likely gas or muscle pain. A heart attack happens deep inside; pressing on your chest won't make it hurt more.
This is not a reliable test and should not be used to rule out heart problems.
2. Location: Fixed vs. Moving
Gas Pain: The pain stays in the abdomen or lower chest. It rarely moves to other body parts Heart Attack: The pain radiates. It starts in the center of the chest and travels to the left arm, neck, jaw, or back.
3. The "Trigger" Test: What were you doing?
Gas Pain: Did you just eat a heavy meal? Did you drink soda or eat spicy food? If the pain starts 30-60 minutes after eating, it is likely digestive. Heart Attack: Can happen after eating, but often happens after physical exertion (walking up stairs, lifting heavy bags) or extreme emotional stress. However, silent heart attacks can also happen while resting or sleeping.

Location: Heart pain typically radiates to the left arm, jaw, or back, while gas pain stays in the abdomen.
The Sweat Test: Chest pain accompanied by cold sweat or dizziness is a major red flag for a heart attack.
Action: If the pain feels "heavy" or "squeezing" and lasts more than 15 minutes, do not wait. Go to the ER or chat with Rua immediately.
