Hello dear Warm welcome to Healthcaremagic.com I have gone through your concern thoroughly . * Symptoms of active TB include fever , weight loss , anorexia , cough in pulmonary issue , lethargy , easy fatiguability , swollen obvious lymph nodes in some cases . * Every lymph node residual in body after TB treatment does not require treatment . * Thorough clinical work up with expert physician is recommended for final decision . Thanks . Regards .
