Hi there, Thank you for your time. I am really worried about a hard bump on my neck, under my ear and next to my jaw. I don't know what it is, but my friend said it might be a lymph node? Its hard and uncomfortable to touch, and doesn't move easily. I feel one on both sides but the one on my right is bigger and more painful. I was feeling it with my fingers, when all of a sudden I felt it push back or even pop maybe, and it flattened and I couldn't feel the bump anymore! It just vanished. I kept feeling my neck searching for it when all of a sudden i felt something move again, deeper this time. The right side of my neck feels warm and it is uncomfortable to swallow now and i am very worried. What might this be and am I ok?
