9 months back, my mother was having 2 swelling seen in neck. We gone to doctor. Ent specialist. After several test like sonography, fnac it was detected as neck tb. There were total 5 in right neck with largest measuring 22 mm the doctor said to go with government medicines for tb. After 6 months course ,again sonography was done. All 5 were there size reduced with largest measuring 11 mm. Then again we were told to continue medicines for 3 months. In end of 8th month, my mother was not able to see properly. Blur vision. So we went to eye specialist, there 2 tests were done. One was for cornea and other for optic nerve damage .doctor said reports are normal and said it is due to tb medicine ethambutol. So he gave in writing to stop ethambutol. So we gone to government hospital to take medicines for for 9th month and told about blur vision. They gave 2 medicines. 1 was rifampicin and other was isoniazid. After taking for 1 month we did sonography again but now it showed lymph nodes swelling in left side also 3 to 4. And in right side largest measuring 10 mm. We told them government hospital. They told course is over. Now automatically it will go. Also vision will be clear. But it pains sometimes in neck. So they gave 1 month medicine rifampicin and isoniazid 1-1 tablet each day. They said treatment course is over but still swelling are there as in sonography. I am worried. Vision has improved slightly but not fully. Also do not know whom to ask ent or pulmonologist? please help.
