Sir/ madam, I had covishield vaccine before 4 days, And I am just received from every one of the effects. Except dry cough and I can feel snot at throat but it's not coming out. Not hungry , I can't eat anything throat is paining like dried up. No one doctor is seeing patients with cough in our area and no medical clinic giving medicine. Sir/ madam, can someone tell me to get rid of that snot and my cough.
