Sir, I usually start coughing at midnight between 2am-3am,sometimes there a bit of urine leakage due to cough. I hav a burning kind of feeling from my sinus part of nose , inside the edge of the mouth only till the neck & not below it (the feeling is as if a liquid is released from nose & travelling till the throat). It's been a month I m gng through 1or the other problem that I mentioned above . Just for information I hav suffered from covid in the month of April (treatment was done at home ,without oxygen requirements).
