[|Human|] I believe I may have an enlarged/swollen lymth node.I am 14 and about a day or so ago i noticed a small lump right unbder my left collar bone: it can move to the top ofthe collar bone and causes a bit of discomfort. My guardian is calling my doctor soon about it but i want to be sure now.I am scared it may be bad. It is about the size of a large pea and i cany lay because it moves. What  do i do?

Lipomas, and bony lesions are other causes.4. To characterize the lesion you need to get an ultrasound scan of the lesion done.5. It will exactly help what content, where it is arising from and how it is involving the adjacent structures.6.Don't worry every thing will be good, be happy. Hope it helps you. Wish you a good health. Anything to ask ? Do not hesitate. Thank you.
