Painful swallowing, 100 degree fever, headache, back pain, s

Hi, The past 2 days I've been experiencing all those: Painful swallowing & burping, 100 degree fever, headache, back pain, sore throat, cannot cough, inflamed tonsils. Before that I was totally fine so I don't know whats wrong with me exactly. I want to know if I have tonsilitis or something else. I also don't smoke or drink. Would ibuprofen help? I took regular tylenol and it seemed to take away the headaches.
