I'm a bit worried about my lymph nodes. About five months ago, a CT scan showed my lymph node was 16mm, and I had another scan today showing it's down to 8mm. I'm seeing Dr. Ujjwal Parikh at Sir Ganga Ram Hospital, and I'm feeling better, but I'd love to get some extra advice to be sure everything's okay. What do you think about these changes, and should I be concerned about anything?
