How much time it will take 28*18mm TB for lymphnodes(stomach) to cure with ATT tablets? My father using ATT tablets from three months and size is reduced now to 23*16mm, some forums says that First phase medinece (used for first two months) should almost eradicate TB from the body, is that really true? We switched to second phase medicine without any counsaltation as two months completed (bcaz of lockdown) is that correct way or we should have used the first phase medicine more??
