I am a male 19 years old 5 10 . When a healthy body, but lately I have been having a slight fever , and the sides of my head hurt, my temples hurt when ever i fart and it feels like there is pressure in my head, I am worried about this pressure. I also had a sore throat this morning, but it went away as the day progressed. What is wrong with my head and why does there feel to be so much pressure?
