Subjectively, certainly the signs are cough, chest tightness, wheezing and shortness of breath. It is best to have an objective test like peak flow to be sure of the severity of the attack. Spacers to reduce the incidence of these infections, so does rinsing and spitting after their use. Pulmicort is a dry powder inhaler which is designed to be activated by your taking a deep breath. I have seen no evidence of a greater incidence of thrush with pulmicort and prescribe it for my patients.
Allergic reactions vary a lot.
They may be manifested by hives on the skin, or with a sneeze and signs of hay fever. In certain individuals who are susceptible, the allergy reaction may be manifested by asthma. If you are already asthmatic, then when you are exposed to allergens that you are sensitive to such as dust mites, pollens, molds, etc. A good treatment program, however, is designed to control these reactions but avoidance of allergens is key. I am not sure I have the whole question but we like to talk about large and small airways.
