I first presented with high fever (103) and typical flu symptoms - including sore throat and what doctor described as sores on the palate. She said it looked like mouth hand foot disease, though that was ruled out since my hands and feet look fine. A strept test came back negative. A couple days later, I am only left with sore throat, including red spots, white ulcers and one bright red inflamed tonsil. Any ideas? Do I need to go back in?
