Lung infection.
I used to get them every year back when i smoked.
The doctor will prescribe antibiotics and probably some inhalers, too.

If you ate a smoker you should probably consider quitting. I almost died to it once and suffered permanent lung damage.
I'll be stuck on inhalers for the rest of my life.
