<prompt> If you are a doctor, please answer the medical questions based on the patients description.hi, i have a cold, runny nose and cough. i have produced some mucus over the last couple of days but this morning i coughed up a 3 inch peice of what looked like throat lining. should i be worried. yesterday i had a temperature of 38.2 but today i am fine and feel a lot better in myself.  <response>: Hi, I had gone through your query and want to say you thanks for your patience despite having such symptoms. I think you need not be worried too much now. I see similar cases in my clinic. In the first meeting, I give symptomatic treatment thinking of viral infection and ask them to follow up after 2 days if they are not improving. Since you are giving history of fever for 1 day, I would advise you to observe for another 2 days. During this time you may take:Antihistamine like cetirizineParacetamolacetaminophen tablet if temperature risesThroat soothing agent you find breathless, wheeze,profuse foul smelling sputum etc., then please go to your local doctor. Hope this answers your query. Take care and get well soon.
