I'm 32 years old with minimal health problems in my background. 2 months ago I started having problems getting a full breath. This coincided with my using a propane/oxygen torch to make glass beads, initially without adequate ventilation. My doctor first diagnosed me with "restricted airway disease" and gave me some Serevent, to which I quickly developed a tolerance. At that point it seemed to come and go - I'd go days without any trouble. It didn't seem to coincide with my using the torch. I went back to my doctor to see if there was something stronger, since the Serevent wasn't working, and she gave me Albuterol, which never seemed to help at all. Now it seems more chronic, and it feels painful all along my upper airway, especially around my throat (but my throat doesn't hurt). I don't have a cough, or phlegm. It actually seems to get better when I'm lying down. It used to get better when I exercised, but now that it's cold it's still hard to breathe. Sometimes I also notice that it feels like there's a big bubble in my upper trachea, like a thick feeling. It reminds me of when you try to eat mashed potatoes too fast and they get stuck halfway down. I hardly ever have problems right when I first wake up, only after I've been up for a while. Does this sound like anything in particular, because all my asthmatic friends say it doesn't seem like asthma.
