What do "normal" lymph nodes look like?

[MrsNikon]

I know I need to consult a Dr., but last time I paid $100 to be treated rudely and thrown some antibiotics.

Anyway, the lymph node under my right ear/ jawline became swollen last August, I went to the Dr. and had the previously described experience and was diagnosed with an ear infection. However, the lymph node has not significantly decreased in size nearly a year later. It was hard and flesh colored for 10 months, although some of the soreness subsided. However, last week it become sore again and I noticed that it looks like there is blood in the center of it. It is now squishy and very sore, and I feel a slight onset of my ear infection again, is that normal behavior for a lymph node? Should the same one become inflamed over and over?

Thanks in advance.
