<s>[INST] Today when I was getting ready to leave for church, I got a sharp pain in my right side of my chest that hurts in the exact same area in my back. I dont have any other symptoms but it does hurt worse when I move. What could it be? Also, I had plurisey 2 weeks ago. [/INST] A sharp pain and on the right side of the chest is less likely to be from the heart, although it would be useful to have an ECG, which is an electrical tracing of your heart, to confirm this. Common causes of sharp pain that is aggravated by movement includes an origin from your muscle or tendons, and sometimes from your lung which is what we call pleurisy. These may occur following a number of insults, including an infection or injury. Hope this is helpful. </s>
