I think you're eating things that are making your stomach bubbly. Alot of these gasses move up to where your heart is. Tell me what have you been eating recently?
Ah. It's traditional food that my mom makes, and I have no idea what it's called. But I do know that some of the stuff, I do not like at all. It's very healthy though, but I gag sometimes when I eat it. It doesn't have a pleasant taste. But I have to eat. I don't want to hurt my mom's feelings or be a ungrateful child. But my body adjusts itself and I get used to the taste.
That's precordial catch syndrome. It's not happening when he breathes so that's not it. You mention food. Ymy mentions gasses which could mean heartburn. Why of all places do you ask here? No one here has a medical degree. Go to the doctor and describe your symptoms. I don't care if you might offend your mom or not. Your health is more important than your mother's possible reactions. Your health should be your top priority.
