I strongly recommend that you go to see your primary care doctor
about this issue if you have not done so already.
The first thing they will want to do is try to sort out how acutely these symptoms of coughing, headache, and wheezing have come on, as this will help them figure out what the potential causes might be.
For example, if the cough and shortness of breath have developed relatively rapidly over a period of a few days, then bronchitis or another lung infection are higher on the list of possibilities, especially if there is also fever. Similarly, if you have a history of asthma
in the past, an asthma flare could come on quickly and cause these types of symptoms.
On the other hand, if the symptoms are more chronic and long standing, then there are other possibilities. For example, chronic sinus congestion or nasal allergies are both very common causes of chronic cough. Asthma can also be a cause of chronic wheezing and shortness of breath, as can bad acid reflux
from the stomach.
Your primary care doctor will be able to perform a thorough examination and help figure out what treatments are indicated to get you feeling better!
