I developed cold symptoms three weeks ago. runny nose, sore throat, cough. took some over the counter cold medicine and sore throat and cough improved. now runny nose and blocked sinus still persists resulting in wet cough at times?

URI recovery: Viral upper respiratory tract infection (URI) is usually self limited but symptoms may linger awhile until full resolution. OTC de-congestion and cough medicine are appropriate for symptomatic relief and prescription antibiotics are usually not required. I suggest expectorant cough medicine and plenty hydration in daytime and suppressants at night time for better sleep.
