Hi,
Asthma is itself a allergic disease due to cold (or dust or pollens or grass etc) irrespective of the triggering factor.
Your asthma actually triggers
bronchospasm which leads to your
wheezing and breathing difficulty.
You can go for pulmonary function tests if not done.
Treatment is mainly symptomatic which might require inhalational steroids,beta agonists,anticholinergics as MDI or rotahaler as a regular treatment.
There are very good medicines like steroids, alpha adrenergic agonists, anticholinergics available in market in all formulations like inhalation, oral, injectables etc which can be effective within seconds even.
To decrease the inflammation of bronchi and bronchioles,you might be given oral antihistamines with
mast cell stabilizers(
montelukast) and steroids (
prednisolone) with nebulization and frequently steam inhalation.
The best way to cure any allergy is a complete avoidance of allergen or triggering factor.
Consult your pulmonologist for further advise.
