hi, i'm not sure if i have mono or the flu. i have been ill for 3-4 days but i am feeling better throughout the day. my temperature is 99.5, i have a soar throat, i do NOT have swollen lymph nodes nor have i ever, i have very small headaches behind my eyes, i have had lack of energy however i feel a lot stronger now, and i kind of/sort of has lost my appetite; but that's because i don't want to eat anything while i am sick.
