I have one small swollen occipital node, but my doctor I showed thought it could be a tight muscle. I work out a lot and may have strained my neck. It’s def stuff on one side. The area seems to get big and then go down. I, tried massaging it, and rubbed it pretty hard. It’s bigger now, which makes me feel like it’s actually a node. And I keep prodding it out of anxiety. It’s not enlarging at all, unless I begin playing with it. Should I be concerned.
