Actually I m having a chest pain from last 15-20 years continuously. Sometimes it stops paining for 2-3 days but again get started paining after 2-3 days like before. And yes I m a smoker but I must say I get started smoking from last 7-8 years back but before I get started smoking then also I was suffering from my chest pain regularly. And now I m also having problem of shortness of breath. Kindly suggest me so. I will be very thankfull to you.
