HI, I had gone through your questions, and understand your concerns.
First of all fat pad seen in your X-ray or
CT scan is not the cause for your coughing and breathlessness. This will not cause you any complication or illness.
From your history I understand that you get cough, mucus production,
shortness of breath and
wheezing since 6 weeks, and X-ray ruled out
pneumonia. You haven't mentioned your age and whether you are/were a smoker. Also you had any previous history of similar symptoms. 2 probabilities are 1) allergic
bronchitis or asthma, if you had similar symptoms in the past or other allergic symptoms. 2) chronic bronchitis or COPD if you are above 35 and a smoker. Depends on the condition you will need treatment with nebulizers, inhalers (broncho dilators and sometimes containing
steroids) or a combination), antibiotics (if signs of infection like colored mucus, fever, raised
WBC count etc.), and may be a short course of oral steroids.
In both conditions there will be excess mucus production and narrowing of airways which cause wheezing. The treatment I mentioned will take care of both. You might have to continue some tablets or inhalers for long time.
Hope I have answered your queries. Thanks for using HCM>
