Thanks for your question on Health Care Magic.
I can understand your concern.
At present no need to take anti tubercular drugs because your report is not showing
tubercular infection.
Report is showing reactive
lymphadenitis. It is seen in bacterial infection. So in my opinion, you should take broad spectrum antibiotic at present.
Wait for atleast 10-15 days.
If swelling is decreasing then no need to worry for
tuberculosis.
But if swelling persists or increase in size or becomes painful then possibility of tuberculosis is high. And for confirmation, you need to get done excision
biopsy and histopathological examination. This will be 100% diagnostic.
So at present, don't worry about tuberculosis. Start broad spectrum antibiotic.
Hope I have solved your query.
Wish you good health. Thanks.
