A long-lasting swollen lymph node behind my ear

I had recurrent otitis media (middle ear infection) when I was 6-8 years old. The infection probably repeated itself for several times later but was not as serious as before. Around 12, a swollen lymph node was found behind my right ear, right above the mastoid process. The swollen lymph node has existed since then and I am 27 now. The size of the lymph node varied (getting smaller) in the first several years but became stable later. Now it is about half an inch long and a third of inch wide.

From some websites, I know that swollen lymph nodes are commonly caused by ear infection. However, many documents also say the swollen lymph nodes should disappear soon after the infection disappears. In my case, the thing has existed for more than 15 years. Although it doesn't cause pain or anything right now, I am wondering if this is normal.

Thanks very much for your advice.
