Is Slight Fever, Chills, Aching Muscles, Increased Phlegm Production Concerning?

Hello, I m punctually ill every December, never any other time of the year. Two years ago I ended up in hospital with an ear infection that caused me severe vertigo. I m scared it might be happening again, but I d rather save the trouble of going to my GP in case it s nothing. I ve got a slight fever, chills, aching muscles, my phlegm production has increased and orange dots have recently appeared, I might have felt slightly dizzy, but I can t confirm. Thanks for reading all of that and I d like to thank you in advance for this is a great, honest, helpful service you re offering. Yours sincerely, Anthony Sowerbutts.
