Deefstes, if you held your breath, it is possible to have pulmonary barotrauma. Dull pain in the chest can be a manifestation of pneumothorax or pneumomediastinum (have personally seen cases of both, one of them in a fellow diver). Pneumomediastinum generally resolves without sequelae, but pneumothorax does not. I would see a physician. (BTW, dull pain that resolves with aspirin, which did not come on with exertion or stress, and in someone your age, unless you are a poorly controlled diabetic or have other unusual risk factors, would not rank high on my suspicion list for coronary artery disease as a cause of the symptoms.)
And just going back to the bag shoot, it is actually a LOT easier, and probably safer, to shoot bags from reasonable depth, than it is in the shallows. Not only do you have to fill the bag more in shallow water, but your own buoyancy is more tenuous.
The big lesson from this experience, I think, is how much care you have to take to make sure the line and bag are completely clear of you, and to keep your fingers where they won't get caught. One of our former regular SB contributors, Rick Inman, took a 75 foot ride to the surface after getting caught in a big bag. Bag shooting isn't difficult, but must be treated with respect.
