My mom, 51, with no medical history but a smoker, recently was seen for a 1-2 day history of chest pain. It was not exertional, but worse when she laid on her left side or took deep breaths. No recent cold or infection. It was right under left breast but she couldn't reproduce it by pressing on it. She had a troponan checked which was normal, CBC normal, and EKG = "nonspecific T waves, can not rule out ischemia". She was told to take ibuprofen as they thought it was more pleuritic? and be seen back. What do you think of this diagnosis and what does the EKG mean? Should she have a stress test?
