Mystery illness

About a week and half ago I had a sore throat come on very quickly while ending my work day. A coworker had come down with strep throat two days before hand so I assumed I knew what was happening to me. That night I drank plenty of hot tea & water & juice. I got plenty of sleep over the next couple days and sucked on cough drops during the day.

By Saturday I was getting worse as I had low energy and was tired. I did not have any of the flu symptoms associated with strep throat and was not coughing. I went in to my health care providers for a strep test and it came back negative.

Last Monday through Wednesday were the rough days. I visited my health care provider for advice & to be tested for mono on Thursday. I felt better going into the weekend and the test for mono came back negative.

Saturday and Sunday were a bit worse as I had zero energy and loafed around the house. I have some sort of virus and no one knows what it is. I hate being sick and not knowing how to treat it.
