I have had laryngitis for 2 days , dry cough for 3 days, watery eyes3 days, post nasal drip for 5 days, and ear discomfort mostly from flying started 3 days ago. Will things get better without intervention of medication? I am a flight attendant exposed to inflight conditions. My sister, whom I have been around, has bronchitis now but 2 weeks before our visit was diagnosed with influenza A and B
