Hello, I am into the 4th week after the start of a cold. Started with sore throat, runny nose, headaches, laryngitis. All that has resolved. I am now left with a lot of yellow flem which has a mildly offensive taste and mild headache and soreness around eyes, cheeks and teeth. Have been to the medical centre twice, and have been told, it will resolve itself in time. Do not suffer regularly with colds. Thanks for any information. Regards Sylvia
