Swollen lympnotes, flu symptoms, hard to swallow?

3 days ago I woke up with a swollen throat, on the right side only. Both of my lymphnotrs are swollen in my neck, by my throat and are very tender to the touch. 8 hours after I woke up with these symptoms, I developed flu like symptoms such as fever, chills, headache, and dizziness (common flu sumptoms) but I didn't experience a site throat, running nose, or cough. I feel much better now, I'm still experiencing the same symptoms with my throat, but it's gotten better than before. My flu is going away as well, I have an appetite. I'd like to get answers before I go to the ER because I dont have medical, so my bill will be very expensive if I were to go, so, any advice please? Thank you.
