Accident resulting in stabbing pain in lymph node/back of jaw

Last night I was at Jui Jitsu class and as to be expected I got caught in a choke hold. As my partner began to apply force I felt a sudden sharp pain coming from one side of my jaw and gave up tapped out instantly. After continuing class with minimal pain I thought it was fine but today it's been really bugging me and a little swollen. While eating I get what almost fells like a pin stabbing into my lymph node. I've had them swollen before from the flu etc. but this feels quite different. Does anyone know if something like that would rupture due to trauma?
