I had allgeries and sinuses for awhile ,then I got headaches for a couple of days ,i lost my voice for two days,now it s coming back,a few not so bad fevers,and today a slight headache and coughing up greenish stuff ,the first time I coughed something up had a touch of blood in it,the rest are just greenish looking no blood in it,when I am able to cough up stuff my voice comes back a lil bit,so what is it ? And does it mean it is breaking up now and going away?
