Hello Doctor..
My father was diagnosed with COVID 2months back he got treated in hospital for 20 days with oxygen support...After coming home he is still on oxygen support ..he is off oxygen for 3 hrs daily.. If he does light walk also his oxygen drops at that time... he became very weak.. before covid he was very active- used to do yoga, walk , everything...His doctor told some people take time to recover ..
He never had breathing issues before but had
diabetes, bp..
How much time will it take him to recover ?
Anything to worry ? Plz help me with his recovery
Thank you so much
