Swollen lymph node+other issues

[Jeli415]

I am a 20 year old female who had her two wisdom teeth on the left side removed approximately a year ago, and ever since then my lymph node has been swollen. For the most part I can ignore the swelling, as it doesn't hurt, but once in a while I will get swallowing pains on my left side and that's when I can really feel my lymph node throb. For a while I had an abscess at the extraction site, but that was drained and no reason was given as to why it was there. I had two x-rays done and both show that there's nothing trapped in my gum (could there possibly be something that's too small to detect?). I don't believe my lymph node was swollen before the operation. I'm desperate for answers because everyone says I'm fine but I don't feel fine!
