Get an ECG to check your heart.
I would go to an emergency room at a general hospital.

Are you sure it's not neuralgia and not your heart? It can also radiate to the arm. Maybe go to the ER to get checked? Blood pressure, EKG, a doctor's exam?

Neurodiclovit really helps me with neuralgia. You take one capsule, and you'll feel better within an hour.
