My blood tests shows that i m affected by tb.. i have a swollen lymph node since past 6 months.. it started with a single node swelling but gradually it kept on increasing to second and third swelling of nodes near neck. Doctors suggest a biopsy. But what do you think m i suffering from this?? I have no other symptoms like fever weight loss etc except fatigue persisting all day long. My coaching asked me to come once i m cured. Is it contagious?
