Lymph node pain

There is a lymph node back of my neck in the left side. Sometimes i can feel it there when i turn my head, if i turn too quickly it hurts alot, like it gets crushed by something, that’s how i can put it into words. Why does this happen? Is this normal? Thanks

How do you know it is a lymph node and not a small cyst/tumor? Have you had it checked by a doctor? Sounds like something that would warrant a visit!
