Generally, TB lymphadenitis
will be cured with appropriate and adequate treatment, unless there is some medical disorder which suppresses immunity. If you have been taking your treatment religiously as prescribed by your doctor, you should have no problem. You have mentioned one indication suggestive of cure that oozing from the neck abscess
is stopped. Another indicator of +ve response is ESR
level (a component of full blood count). If it was abnormally high (before diagnosis and commencing the treatment) and now if it has dropped towards normal level, then it means you are improving.
