Non cardiac: Chestpain could be from other causes also. You may have reflux with esophageal irritation/ulcer, or spasms ca cause pain. Have it looked at by a gasteroenterologist

Probably not cardiac: Just curious - were cardiac enzymes & CRP part of the blood work? This is a good number of tests already. Given your age & negative tests, I doubt that you have heart disease right now; but about 70+% of Americans will get it at some point in later life (50s). Chest pressure can be related to acid reflux / ulcers or muscle strain, which may be the next thing to investigate. Talk to your doctor.
