My right eye stings and is watering, my right ear aches, my right gland is swollen and my right nostril is blocked and keeps running, I also have a slight cough , left side is all fine... I guess it s a common cold , but why is the right side the only side experiencing symptoms? Also, I m Cabin Crew, would you say it was safe to fly in this condition, I ve been told stories about an ex employee who went deaf in one ear from flying with a cold.
