Swollen painful neck glands, fever 100.6, chills, painful to tilt my head back, headache, and sore throat.

Maybe strep, etc...: Nose and throat symptoms can be from cold viruses, strep throat, allergies, etc... It can be difficult to tell what the cause is. If symptoms only last 1-2 days, it is more likely allergies or irritation. Doctors have rapid 5-minute tests for strep, so a primary care doctor can diagnose strep and start antibiotics without delay. Sounds like it's time for a trip to the doctor.
