I have costo-chondritis currently and have had it for about 2 years now. When this started or around this time, i noticed a bump behind my ear. I asked my pediatrician and he said it was a lymph node and that those come up when fighting an infection. But it is bothering me now because it is still swollen and has been for a long time. Could it still be swollen because it is helping me with the swelling from cost-chondritis? It also sends pain through my head, neck, and arms sometimes. That is mostly towards the end of the day though. It's been worrying me for sometime and i was hoping I could get some advice and clarification. Thanks.
