Feeling sick

Brooke
So I've had swollen lymphnodes under my chin for about 2-1/2 weeks. I took my wisdom teeth out Tuesday last week and have had a fever since then every day. The lympnodes went down but still have a fever. 
Have been taking Advil for about 2 weeks and hydrocodone along with my prescribed antibiotics (amoxicillin) my teeth feel better, still some pain but I keep having a fever! 
Any doctors and nurses know what this is or if I should be worried?
