pains in the chest can be from gas.

As we age we don't digest milk products well, and they can cause gas.

Also, people who are anxious often swallow air, without realizing it. Then they get gas pains if the gas gets trapped.

Gas-X is a simple remedy and works well. Most places have it, commonly in groceries and drugstores, etc.

If you have been worked up by a doctor when you have the pains, and heart issues are ruled out, then think gas. You should always have chest pain evaluated to rule out heart issues.

Some people do get inflammation of the cartilage in the ribs.
This is called costochondritis. It often responds to anti-inflammatory drugs like ibuprofen. This type of pain does not go away with Gas-X treatment.
