I'm feeling worried because I've been having arm pain alongside chest pain. I've already had an EKG, some blood work, and an X-ray, and all the results were normal except the EKG, which showed some abnormalities. What might be causing this?

Given your symptoms of arm and chest pain, and abnormal EKG results despite normal blood work and X-ray, possible causes could include: musculoskeletal strain, costochondritis, pericarditis, or gastroesophageal reflux disease (GERD); however, the abnormal EKG result warrants further evaluation, so consider consulting a cardiologist to rule out underlying cardiac conditions, such as myocardial bridging, coronary artery spasms, or cardiac syndrome X.
