I've been having headaches, slight body pains, slight fever, pains in my jaw on both ends by the bottom part of my ear, I've been coughing now and again throughout the day, behind my ear hurts occasionally , almost everyday I feel these symptoms. I went to the doctor before but I had a high fever, and bad body aches and he diagnosed me with a kidney infection. If prescribed antibiotics but that was a while ago so those are finished. I'm not sure if it's the same problem or could it be something different?
