I've Quit smoking 12 days ago
After day 10, I started having shortness of breath, chest tightness and phlegm in my throat. My question, Is shortness of breath ok, or should I worry. Also, I cant spit the phlegm in my throat. Is swallowing it harmful?
I am 34, smoked for 10 years, 5 a day. I never had cough because of smoking and now even after I quit smoking.
