Stopped smoking over 2 weeks ago..and im coughing worse like im still smoking and coughing up phlem, i've had flu like symptoms and body aches?

Smoking cessation: It’s not uncommon to have increased coughing after smoking cessation. It is because years of tar build-up is loosening and must be expelled from the lungs. Cigarette smoking destroys tiny hair-like projections lining the respiratory tract called cilia. When you quit smoking, the cilia need to repair and regenerate themselves. Coughing is often due to the reemerging cilia. But you should see a doc.

Congrats!: People stopping smoking will frequently experience a period where they are coughing soot and tar. If you look at your sputum, you will see very small curls of these substances. When people smoke, the cells which push out inhaled junk with little finger-like "cilia, " become denuded. After quiting, they grow back and bring up what has gone into your lungs. The flu like sx may be nicotine withdrawal.

Viral?: It sounds like you may have a viral infection causing your symptoms. If these symptoms are not improving, see your doctor. Congrats on smoking cessation! what a great accomplishment!
