Hello and welcome to HCM,Hypersensitivity
is a condition characterized by inflammation of the lung tissue (or lung parenchyma).Pneumonia
can occur due to multiple causes.
Infection with bacteria. virus, fungus etc is the most common cause.
Hypersensitivity is aless frequent ut a common cause of pneumonia or pnemonitis.
Since, you have a history of asthma
, you already have a disease of hypersensitivity.
Asthma occurs due to increased responsiveness or hypersensitivity to the environmental allergens.
You are prone to other hypersensitivity disorders.
As you have mentioned that you were working in an environment where there was an exposure to allergens (old ceiling), there is every possibility that you have developed hypersensitivity pneumonitis
due to exposure to the old ceiling.
Now you need to take treatment for hypersensitivity pneumonitis along with asthma.Consult a pulmonologist
for further management.
You need to avoid contact with environmental allergens in future as far as possible.
Thanks and take care
