question: Hey recently my friend has had really sharp pains in his chest on the left side. He sometimes get these sharp pains in the middle of the night that wake him up out of sleep. He has had these symptoms this last week but other that he usually has chest pains all the time off and only recently has his chest swollen on the left side and he has also told me that it feels like the pain has kind of started to spread to his whole chest. What do you think he should do? Im really worried.
