I recently had a high fever for 4 days straight, followed by a sore throat with no swelling in the glands or pus in throat. what the hell am I having? The docs I have visited don't know, and I don't want to pay $150.00 on a blood test. I have only had two sexual partners in my life and seeing that most STDs manifest shortly after incubation, and i haven't seen anything in years, i am ruling them out.
