Since my husband was told he has dust mite allergy and should start injection treatment, I've been reading online about it. His symptoms are chronic throat-clearing and coughing, which have been going on for years. He says he coughs and clears his throat because he feels like there's mucus that needs to be expelled. He doesn't have watery eyes, runny/itchy nose, or sneezing. I know from other things I've read that his symptoms could be caused by many other problems, but the allergist was the first place his doctor recommended. So what I'm wondering is should he start the treatment? If it is an allergy that's causing his coughing, will we notice improvement right away? He did start using a prescribed nasal spray, but while he was at the store he picked up Mucinex, too. He says the cough is better. (I haven't noticed yet because we work opposite shifts.) However, now we don't know if it's the spray or the Mucinex. He's tried getting an appointment with a pulmonary doctor, but the wait is several months, so he doesn't want to put off starting allergy treatment.
I know this post was a while ago, but did you ever figure out whether it was the Mucinex or the nasal spray that helped? What was the medication he was prescribed? I am not a doctor and can't diagnose him over the internet, but I think he could have waited on the Mucinex to see if the prescription had an effect first.
Did he every get to see the pulomary specialist? Please consider returning to the site to let us know what you and your husband have learned. I'm sure what you've learned through his experience can help others in the community!
Best of luck,

I might try a dust mite cover like you can get from a site like this: http://www.allergyguarddirect.com/Allergy-Mattress-Covers/Allergy-Mattress-Covers.asp
Sometimes, that is enough to get rid of the symptoms.
