I have experienced sharp pains in my left side of chest. It began exactly one year ago. I have done 4 ekg's, a series of blood tests and nothing seems to be wrong. My back and ribs also ache especialy when I lift slightly heavy objects like 25kg. I'm 40 and I worked long hours for the last two years but now I have toned down because of the above problem. I have been given different diagnosis like Panic attacks, depression and Rib cage inflamtion. For the Rib cage inflamtion, I've had medication (anti inflamation tablets). Nothing has worked so far. What could be the problem?
