Hi, about a week ago me and my boyfriend were hanging out and with the next 24-48 hours we were both bad off. He had a fever of 104 and I was keeping a low grade fever. He got put on a Zpack and is getting better. He was tested for mono and it was negative and a rapid strep test which was negative. I went to the doctors a couple days later with symptoms of a red, swollen throat with yellow patches. I also have an upset stomach, no appetite, and headaches. The doctor said my rapid test was negative and that I probably had mono, but to me that makes no sense. What could this be?
