I would recommend that you have your air ducts cleaned. Air ducts harbor all kinds of allergens, irritants, mold, bacteria...
Also, the drier air from the furnace could be irritating your air passages.
You are always entitled to request a second opinion. You might want to schedule an apointment with a different primary care provider and see what they say about the wheezing and your other symptoms. Many people have a "wheeze" without having ashtma.
I have noticed upon waking up in the morning or middle of the night that I have this feeling of dryness! I can't hardly breath the air is so dry. I have to go wet my hands and use lotion. My mom used to get this when I lived with my parents - when the furnace was on. I hope that makes sense (especially the hardly breath part - it is like when you are talking you skip some words or they come out about half...I have had that then I tell my husband when he looks at me weird - dry!! Lol. I just wonder if we also need a humidifier, would that help?
Yes, a humidifier could help. Just make sure that it is one that will regulate the humidity in your home. I can't remember the optimum levels right now, but you don't want to promote mold growth with a humidity that is too high. That could cause other issues.
Thanks. I will try that then. :)
Hi, welcome to the forum. It is quite important to rule out the cause of the cough, at the same time exacerbating factors, such as exposure to environmental tobacco smoke, dust etc. In your case it might be furnace. It should be pointed out and further exposure should be avoided. The type of cough in his case suggests cough dominant asthma. This may be seen in association with the factors like cold air, sleep, or allergens.
You may need to undergo certain tests like allergen test, spirometry etc. Treatment includes cough suppressants, a trial therapy with bronchodilators which will help to relieve wheezing symptoms, avoiding triggering factors, and available home remedies like use of honey and echinacea.
I suggest you to consult physician specialized in respiratory medicine for evaluation and prescription and above drugs. Take care and regards.
