today during training my lung (I think thats what it is anyways, behind my pectoral muscle on the right side), started to get sore and i experienced a mild pain whenever I would take a deepbreath in or out. I remember about a year or so ago i experienced somthing like this but i don't really remember how it resolved itself. Has anyone else had this? should i just keep training as normal or chill for a few days...I really want to keep training b/c i have some diving coming up in the very near future.
