I've been on treatment for TB in my lungs for about 80 days now, and while I've noticed I'm not coughing as much, Ive started getting yellow mucus in the mornings for the past 15 days. Sometimes it even has a bit of blood in it. Is this something to worry about? Will the coughing go away completely, and is it normal to see blood in the mucus? I've attached my CT scan report for you to check out.
