answer:Think back—is this how you’ve felt before prior illnesses? For me, my first symptom of an oncoming cold is being really tired and sneezing many times in a row, not so much chills. I haven’t had the flu since I was a child, so I can’t remember what the onset was like, but chills can definitely be a symptom of the flu. Have you taken your temperature today? Popped some aspirin or vitamin C? I hope it’s not the flu, and in any case I hope you feel better soon.
