Dear sir, My name is Tammayya. Actually 3 months back I suffered from covid. But with a week dose prescribed by doctor, I got cured I think. But right now I am feeling pain in chest and difficulty in breathing at sometimes. Whenever I took a headbath and if I am staying in A.C, I am unable to stay. I also used to continuously cough through out the entire night. I am unable to sleep. Also there is a continuous secretion of phlegm whenever I cough. But all these times I never felt feverish. From one month onwards I am unable to sleep at night properly. I used to wakeup many times and without sleep you know how everyone feels. So please kindly suggest me some medication for the above problems.
