My husband is a very active man in his mid 30s. He is outdoors a lot on the weekends. He has been complaining of a sore neck for about a year (I am not sure if that is related). Lately he has been getting "colds" often; at lest once a month. All symptoms have gone away after 2-3 days other than his cough; he sounds like a smoker (he does not smoke). He has had this cough for about 2 months. This past month he has gotten a "cold" with the same symptoms every week (lasting 2-3 days). He has ran a fever of 100-103, had muscles aches, chills, and sever sweating. He describes the aches to feel like the flu. Today he says when he coughs he can taste and smell chlorine; and his sputum smells of chlorine. What could be causing this?
