My wife, age 62, got what we thought was a cold or flu on or about Monday, March 6. She had headache, sore throat, but her temperature was never higher than 100 deg. She developed a cough which got really bad on Thursday, March 9. The cough sounded like a lot of phlegm was in her chest but the cough has been unproductive, and now I can hear a gurgling or crackling sound when I listen to her breathe. Tonight she is unable to sleep since her chest sounds are really bad when she lays down. Email address is: YYYY@YYYY
