I have a sore throat; two nights ago it was so sore I could barely talk but it has improved since then but is now kind of getting bad again. I also had a really bad headache/pressure in my head and was so tired all I wanted to do was sleep but again that has subsided. Now I have a tightness in my chest and I ran a race this morning in which breathing was more difficult than usual. Yesterday I also coughed up a little blood and mucus but I haven't been coughing much otherwise.
