Tight Under Ribs?

[[old] johnhgough]

I have recently noticed feeling tight in the chest under the bottom rib whilst rowing, similar feeling to a stitch. what is the advise on avoiding this? should i stop the rowing for the session as soon as i feel it, should i slow down or should i try to breathe deeper ? <br /><br />John

I'd slow down or stop to recover, then start rowing again and repeat.
