Rode Trainer for 30 min.

Typical 5 Min warm up, followed by 20 min of varying work, and 5 min cool down.

Suffering from a chest injury that I don't know the cause of.  I began to notice on my run yesterday and it got worse today.  At this point I am stuck with shallow breathing because when I take deep breath it feels like someone is stabbing me ( on the right side, otherwise I would be in getting my heard checked)
