What causes pain in the sternum and left arm?
Patient: I have a hx of MI with stents; last night I had sternum pain radiating to left, light headedness, left arm pain down to elbow; after SL NTG I was able to lie down and go to sleep Today, my sternum is still uncomfortable with pain in left shoulder blade intermittently and light headed again. Could this be another MI or just angina? Doctor: Hi,Given your history this can be MI or angina again.I would advise please go and see an ED physician.It would be of worth doing an ECG + troponin during an episode of chest pain. Wishing you good health.Regards.
