hi and thanks for the query,
It shall be logical to check for recurrence of TB. A chest X ray, sputum examination for direct examination, culture and sensitivity tests might be useful. It is also advisable to get a bone marrow biopsy
done, to exclude lymph node TB or a lymphoma
that could have similar clinical features. A complete blood count
could be useful in showing the number of white blood cells that could give a further diagnostic orientation for further testing.
I suggest you revisit a pulmonologist for a complete clinical evaluation and management.
thanks and best regards,
