I'm a healthy, active, 15-year-old boy (5'9", 132 pounds) that is experiencing something that really frustrates me, and I'm curious for answers as to what may be causing it.
About three weeks ago, I was sick (it is just a normal sickness, tiredness, sore throat, mild coughing) but what was the most outstanding symptom was my tiredness. I am a high-school wrestler, and I am extremely fit, but every time I would try to practice, my muscles would become fatigued quickly, and I was extremely tired and nauseated to the point where I could barely run. About a week had passed after that, and I would have sore throats in the morning that would require that I drink water immediately upon waking up. The sore throat would subside throughout the day but come back the next morning. As of today (February 7), I have been tired, every day, for the past three weeks (but no sore throat for about 1 week). I get tired fast during practice, and I have trouble focusing. I experience a lot of light-headedness when standing or doing anything physical really. I used to be able to run for miles without much fatigue at all, but now I can't even do a slow jog for gym class without feeling very heavy and wanting to quit. I don't feel like I want to do ANYTHING that requires much physical exertion. This frustrates me because I'm a very active person normally and I love getting work done, staying motivated, being physically capable of many things. I've collected some stats that were recorded today if they may help answer my questions: 96.8 degrees F temperature. 98 over 57 resting heart rate. Although this sounds like someone who is very sleep deprived, I can guarantee you that I get plenty of sleep.
Thank you for reading, because I can't wait to get back into a normal, active (and non-tired), life.
