When to talk to a doctor if you think you have the flu?!

I’m on day two of sudden, violent sickness 😣 sore throat, runny/stuffy nose, sinus pressure, ear pressure, migraine, nausea, vomiting, cold sweats, and my arms and sometimes legs are randomly going tingly like they’re asleep??! Yesterday I could barely stay awake and only got off the couch to go to the pee or throw up. I’m drinking water and eating crackers. Is there a certain point where I should call my doctor? Or go to the walk in clinic? Please let me know your thoughts or rule of thumb, I’m miserable!
