My sister of 16 years is suffering from lymph node tuberculosis of right supraclavicular lymph nodes. It's been 6 months taking treatment. And 5 times doctor has taken pus out with a needle and even if we take it out still the size is increasing and they have done operation at that place to remove pus and wound is open so very very little amount of pus comes out when we change bandage. But again around that area there is major swelling. Can I please get any of the suggestion. And we are in a situation of not understanding what to do. Please please suggest something. And we are worried if it is drug resistant to.
