For the past few days, I've noticed my appetite has curbed (I can't eat as much in one sitting as I used to without feeling like it might come back up, which I've otherwise NEVER experienced when I've over-eaten over the course of my life,) I am feeling fuzzy or light-headed and my skin is hyper-sensitive, even washing myself with a wash cloth is painful. I also have terrible aches and pains in my joints and sides. I've noticed that my tonsils are also slightly swollen, not painful, and I have a runny nose but no cough yet. Does this sound like a run-of-the-mill cold or flu, or something else? (I'm a 24 year old female.)
