[|Human|] Hi I ve had a swollen lymph node on my neck for about two months. It s not painful nor does it move when I touch it. I feel fine no sickness and have had an ultrasound on it. It showed no abnormality. My doctor said it was due to my two year old catching all kinds of bugs but he has not been sick or around other kids much at all. I m just after a second opinion on whether or not to ask for a biopsy. I have lost a bit of weight (not much) and find it hard to sleep at night because I get so humid but not sweaty even with a fan on.
[|AI|]  Hello, Well I would like more information if it was possible like: the localization(behind the ear or above collar bone etc.), other symptoms if you had when the lymph node appeared (like fever, sore throat etc.). As I don't have them and reading your history I would suggest maybe to ask for a biopsy. The fact that it doesn't move, or it is not reduced through this time, and you get humid while falling asleep and the lost of weigh, it is indicated for a follow-up. Maybe you can repeat an ultrasound, a blood analyze (looking for leukocytes) and then the biopsy. If you can't do all this again, go directly to biopsy.(a swollen lymph node more than 2 weeks and not painful doesn't move it is indicated the biopsy). I hope my answer will help you, Wish you the best!
