I have had costo for years. You don't say how old you are. I am 51 and in the last 5 years it has shown its ugly head alot more often than ever however the good news is its less severe.All I have to do now is rest and take some aspirin. I also have had EVERY test especially for the heart. AS soon as you say chest pain look out they iommediately think heart, Then lung, and can never find anything there either. I have learned to live with it after all these years amd try to avoid heavy coughing, laughing anything which might aggrivate it. Wriet me back I would love to hear from you
