I was having a small lymph node in the posterior part of neck for many years. Now, one day I had a slight pain in my neck and yesterday I had observed that my lymph node has enlarged a bit but it can't be felt that easily and it's neither visible from naked eyes and even if I move my hand slightly over my neck most of the times I am not able to feel it. For your information, I had Tuberculosis of Lymph nodes back in 1999 when I was a kid. I took treatment for 09 months. Is there a possibility that my tuberculosis could have relapsed after so many long years. I am also attaching a copy of CT scan of my neck which was done while I was ill in 2018. Please see and guide me.
