For the past week or so, I have continuously felt like I m breathing very cold air. (It s gotten very cold in CT for the past 2 days, but was above freezing when this started). I get this sensation deep in my throat and in my lungs. In the past two days, I ve also lost my appetite. I have not had a cold, sinus issues or a cough in recent weeks, but did about five weeks ago. Not certain what s going on, but it s getting uncomfortable. I d appreciate suggestions on how to alleviate the coldness in my lungs.
