Common cold. As any other serious illness laryngitis is often confused with another more simple ones, in this case, cold or upper respiratory tract infection. People just ignore all the symptoms and their improvement within weeks. A common cold is just a top of an iceberg and has the same symptoms but in smoother form. Laryngitis doubles all the symptoms and has more serious consequences. A runny nose, coughing, and pain in your throat may confuse you, but try not to ignore those symptoms and keep laryngitis in mind.
