Could I be immune to TB, if the blood I got had antibodies in it?
I frequently have bad colds where I'm coughing
up lots of phlegm of diffrent colors, yellow, orange , green, or blood tinged. I used to get sinusitis and or laryngitis all the time untill I started using a Netti pot. My kids have the same colds as me for a week or two, but I cough for a month or more, often just when I'm feeling better another cold starts everything off again.
