In December, There Was A Lady At Work Who Had

in December, there was a lady at work who had a very bad dry cough and 5 people ended up catching it from her. the symptoms were a sore throat followed by dry cough, followed by complete voice loss and terrible hoarseness. Sometimes you could feel a tickle or pain on left side eustachian tube. One person's doctor diagnosed oesophagitis and mine diagnosed laryngitis. After no antibiotics and letting it clear up itself, the left ear persistently pops throughout the day and the left nostril keeps bleeding after nose blowing. I do not understand what is going on and should I be concerned? How do I stop the ear popping and frequent nose bleeds?
