Im a 17 year old female and about a month ago i had swollen lymph nodes in my armpit, now they have moved to my neck. should i see a doctor?

Nodes don't move: The lymph nodes are little filters for body serum that remove debris, germs & viruses. They swell up when working & usually shrink back down in 3-4 wks. Their position is stable though their size & character changes. Armpit nodes deal with that arm or nearby skin. Neck nodes deal with mouth,throat or near skin issues. If they hurt or really spook you get seen.
