Hi I'm 25 years old guy! I had a throat pain 2 weeks before, then followed by runny nose and cough! After 2 weeks I have cough which is getting slowly better! But I am having chest pains which is not so painful and I'm feeling too weak like I'm feeling my heart bit's. I was a smoker but I quit last month, although I was smoking a lot less in the pat 3 4 months. I am so much worried about chest pains! Is this something else! I'm still coughing but lesser than before! Do I have to see the doctor immediately?
