Thanks for coming to HCM
your wife has got extrapulmonary i.e uterine TB for which regimen is 2HRZE/4HR. It means that AKT4 was extended for a month which can be done if there is inadequate response. now inspite of monto3, monto 2 has to be given as per the guideline.
, one of the constituent of AKT4 can lead to hyperuricemia
and joint pain but you are off the drug i.e no pyrazinamide is in monto3...so now it is not the culprit..
for pain you can take analgesics like ibuprofen
etc........ and go for certain test like RA factor, ANA, ESR and if RA comes out to be positive go for anti CCP test which will confirm rheumatoid arthritis
It will better to relieve your symptom by analgesic ant to meet the doctor with the abovesaid tests....
