Chest cramp on left side. unsure if it's heart. stingy neck pains randomly. ekg, x-ray, heart enzymes all were good 2 weeks ago. heart issue?

Unlikely to be heart: Typical chest pain in a male is not described as "cramp" and unlikely for cardiac enzymes and EKG to be normal if performed while having chest/heart symptoms. More probable is that your neck pains are from a "pinched" nerve, mechanical trauma if you play sports and chest camp may be rib pain. In other words, your symptoms seem more musculoskelatal. Might see a physiatrist or neurologist for MRI
