long would it take for the lymph node to subside?

hi Doctor, i have been diagnosed Tb involving lymph node on the right side of my neck. the test taken were FNA, ESR, LDH and CPR. i have been taking the first line drugs for the past two months now. took out further tests which show my ESR has come to normal from 62 and so goes with LDH and CRP. lymph node has also decreased to a fraction but not all of it. my question here is that how long would it take for the lymph node to subsidies completely. thankyou.
