Hi There. I'm 16, and two weeks ago, I began having a slight cough and cold...I moved last summer, so I attributed it to allergies flaring up, due to uncommon pollens and stuff in the air. It began overnight...the next day, I was incredibly tired, nearly falling asleep in all my classes. Then, I went on to getting a high fever, really bad chills, a loss of appetite for the most part, and a worse cough and cold. Over the past few days, (on my right-hand side), one of my upper teeth has begun to hurt really bad. Now, with my tooth, the pain will flare up really bad, and then it will slowly subside a few hours later. The same thing with my other symptoms, I keep getting better, then relapsing. Except, for my cold. It has remained horrible the entire two weeks. I even got a nose bleed in the middle of the day last Thursday...I have used up so many boxes of tissues and rolls of TP, blowing my nose...What is wrong?? Is it maybe a sinus infection?? All suggestions and ideas are MUCH appreciated!! Thanks.
