I'm 22 with 2 swollen lymph nodes on 1 side of my neck for 7 months. they are painless, soft, kinda movable, small, & have not grown. should i worry?

Lymph nodes: Probably not. Probably they are reactive lymph nodes- either from chronic inflammation on the throat or something in your mouth like gum inflammation or tooth problems etc. Since they have been there for 7 months- next time you see your doctor bring this up so your md can examine them. If you're worried or if they grow , absolutely you should see your md sooner to evaluate more.
