Thanks for your query.

Yes, there are chances of recurrence of Tuberculosis if the TB strain involved was resistant to the drugs you were on for a year and half. In addition, faulty dosage and irregular medication can also lead to such recurrence. It is very common with Tuberculosis to recur.

Other cause for such a recurrence of abscess in a lymph node previously affected by TB could be by a bacterial infection. This happens due to altered morphology of the lymph-node tissue affected by TB making it prone to be affected by other virulent bacteria.

A better modality to test whether it is a recurrence of Tb or a secondary bacterial infection is by getting an FNAC (Fine needle aspiration cytology) done. In this test, a small amount of the tissue from the lymph node is drained using a small needle and examined under the microscope. This gives a detailed idea about the exact diagnosis.

Hope I answered your query.

Please do let me know if there are any other concerns.
