I just noticed I have a sore throat with what looks like redness and little white bumps in my throat. My knees have been swollen for a few days. History of rheumatic fever as an adult, scarlet fever as a child, and currently taking Tapazole to treat Graves Disease. It is Saturday, and not sure if I should go to an emergency room tonight or to urgent care tomorrow, or maybe wait until Monday to get in to see my doctor.
