It was a swollen lymph node in the left neck, which I was monitoring lol, for three or four months. Then I had an abscess on my face, probably from shaving, breakdown of the immune system, and required surgery removal, and pointed out the swollen node at that time to the hospital, which was attributed to the infection, but it evidentially was not when checked a month later by FNAB, CT by the ENT. I guess sometimes they should look outside the box, and there can be co-infections, diseases, illnesses, not just the obvious one.
