My mom has recovered from covid. She was suffering from severe pneumonia and now she is fine. But the moderate cough is still there. My actual question is while she is in laying down position she goes to change the sleeping position or turn left or right (karwa badalna) suddenly the coughing begins. While sleeping straight the coughing is not observed but when she changes position the coughing begins may I know why is this happening? And what to do so she can get rid of this thing?
