No, they don't necessarily go hand in hand. I had allergies from birth to age 50 before a bout of walking pneumonia dealt me asthma. And my allergens rarely ever set off my asthma. Asthma issues will me seem to climatic - too hot and humid days mostly.
hi sorry for sticking my head in, but i also used to smoke and had lost of bronchitis and since stopping the fags and having the walking pneumonia it has also lefty me with a horrid type of asthma that gives me pain and imflamation more in my right lung and a very dry cough i think a lot of people who quit then go on to be asthmatic dam!!!!
My asthma also emerged 2 years ago following a respiratory infection. I have no known allergies but I am highly susceptible to irritants. I don't wheeze but do get SOB and cough severely (usually dry).
Physical exertion, fragrances, smoke, temperature variations and humidity all give me problems.
I had my asthma confirmed by a methacholine challenge test ordered by a my pulmonologist. He also had me see an asthma specialist at the University Lung Center who also confirmed it as cough variant asthma but without allergies.
I've had non-allergic related asthma since birth ..10% of asthma suffers are non allergie related. It really seems to confuse the average doctor and we seem more prone to humidity related attacks (my pumologist said that ).
