Welcome to HCM
After going through history ,you started with a viral respiratory infection
with secondary bacterial infection now you are recovering.
Many times such infection makes lungs hyper reactive and inflamation and bronchospasm
just like a asthma.
You have taken medrol for short time some times such episode may take 2 to 3 weeks to recover completely .
Please consult chest physician to see any bronchospasm is there or not ?
A Pulmonary Fucnction test may be done later on.
along with oral steroids
will help in recovery.
Good Luck to YOU
