I have been suffering from tuberculosis lymphaneditis for 6 months. Now I am still taking medicines but there are another knot developed on my neck just above the old knot now sir what should I do. Is it the sign of MDR tb or what.i took tb medicine after breakfast for four month but I took these tablets at night for one month because of Ramadan (A Muslim fasting festival). But again I started to take it on my old schedule. Then can rescheduling the drug period also cause this problem I. E another knot development. Please sir suggest me I shall be thankful to you.
