Re: Sudden chest pain on upper right side
This is probably not heart, but unknown chest pain of any kind that persists for more than a day (or two depending on the severity) should be checked. Pain from deep breathe or movement could be bruised/cracked ribs (if you've had any injury), some kind of lung/respiratory issue, or muscle strain. It could also conceivably be heart, it just doesn't sound like that to me.
If you're in a lot of pain I would go in today. If is tolerable and seems mostly associated with movement I would give it another day.
