Sore throat, no other symptoms besides pressure in my head after I wake up. What are usually the "worst" days of a cold?

In brief: Days 2,3,4

Headache and throat symptoms can be from flu/cold viruses, strep throat, allergies, etc.
, except that allergies usually don't cause a fever. Doctors have rapid 5-minute tests for strep, so a primary care doctor can diagnose strep and start antibiotics "right away", which means within the first 3 days of a strep throat infection. Doctors also have a 15-minute test for Flu A and Flu B.
