Hi, I’m a 20 year old female who has got 4 small pea sized lumps under the skin in my neck, they are not visible I only know they’re there from touch. They are moveable but painless and haven’t grown since I found them in 2020, they are hard but can be moved around under my fingers, one is near my collar bone and the others are near my hairline. Of course I google and then start to think the worst, could they just be lymph nodes that haven’t gone down?
