I haven’t had a cold in 18 years, but recently just had a sinus thing that went into a cold. … I could feel it settling into my lungs and didn’t want any part of that, so I put a magnet over each upper lung, where the soreness was. There was immediate relief. It did not stop the lungs from getting the gunk, but it certainly made it easy to cough the gunk out AND kept the pain away. Since I had childhood asthma, colds always went straight for my lungs and the pain was always bad.
