Degree sun symptoms and conditions

I was taking this drug after having surgery on my foot. After taking this pill twice a day for 5 days, I woke with a high fever, chills, headache, nausea and could not sleep. I continued to take the drug thinking that I just had the flu, my symptoms continued for the next 2 days. My fever broke the morning of my 7th and final day of taking this drug. That evening my fever came back and I broke out in a rash (front/back/arms) and my skin looks like I have a first degree sun burn especially my face and chest and it itches. I had not been out in the sun the entire time of taking this drug.
This will be the last time I I take this drug.
