Re: coughing after long shooting session
I don't know what your access to healthcare is, but I'd encourage you to see a doctor. There any number of things you could be reacting to, and your lung function may, or may not be returning to normal between episodes.
I don't know how to setup links- I, but Web/MD has a place you can plug in symptoms, and get some feedback. It won't substitute for an exam, but you'll have better questions to ask when you see a doctor. Good Luck
