What Causes Sharp Pain Radiated Across Front Rib Cages?

Woke this morning with what seemed almost like painful lungs, but then the sharp pain radiated across under my front rib cages. It kept getting stronger, was not relieved by sitting or standing. I tried to pace. Felt faint so I sat back down. My breathing was difficult. I broke into a cold sweat or heavy perspiration. Felt a little nausea. After an hour it started to subside. I went to the recliner and covered up. I was freezing. Still dont feel 100%. Steady slight pain in my back, behind left ribs. Tolerable. I have eaten today without problems. I eat pretty health and excercise daily. Did I have a heart attack? Gallstones? Kidney stones?
