I Have A Viral Cough . I Smoked For 5

I have a viral cough . I smoked for 5 years 2 to 3 piece cigrate per day . Now I quit from smoking . From last 3 weeks I not touched it . And I'm feeling bad uncomfortable chest pain and burn . Pain and burn is not at particular place it's come and go many times at many place . And some times pain stay for hours . Is it common after giving up nicotine ???
