Low grade fevers 99-101.7 for 1 week, headaches, lots of sneezing, wheezing, and coughing, and also yellow phlegm, and I have a weird sharp pain in the area around my heart…. I'm 15ish years old…. (If that helps… 
) all of the symptoms have been happening for about 3 weeks in total. I am not allergic to pollen or anything else except some airborne mold, and my house (supposedly) doesn't have that.
