Do I have a cold or flu or something else? I've never had something like this I have a scratchy throat & mild fever of 99.5and a little burning in nose

Cold. It's very hard to say as you don't say when the symptoms started. Ig it's the flu in a few hours you could be much worse. At this point it sounds like a mild virus. You're very lucky to make it this far with never having more problems than this.
