Why do some people cough all the time for seemingly no reason?

I don't remember not having it.

I have mentioned a few times that I was from the ghetto, so to appear tough, I smoked from age 12 into my 20s, or I might have outgrown it.

Allergic to mold, dust, ragweed (which I got allergy shots), dogs, cats, eggs, chocolate, nuts, feathers.

Stress triggered attacks until I was about 14, but then that stopped.

In my mid-20s, I became very physically active, and other when I had a chest cold or the flu, the asthma didn't bother me much, to the point where I had a German Shepherd, an Irish Setter and 8 cats in a studio apartment. I often forgot to take my medications.

This lasted into my 50s, when I stopped having cats or dogs because I couldn't bear to watch anymore of them die.

I also ceased physical activities in my late 40s due to severe back problems.

I was okay (as long as I took my medications) until about 5 years ago, when the asthma came back strong.

But all during my life I have coughed, and produced serious lugees at least 4 to 5 times a day. Produce them much more now. 

I've always had an emergency inhaler with me.

Of course, cold weather has always affected my breathing when it is under 35 degrees.

My life has become very limited, and I wish to die. But I would like to spit a SERIOUS lugee in the OPs face first.

Now please stop breaking my balls. That's all I ask
