@ Dreamy_SirGwaine actually, it's kinda high for fever having 39.6°C, but nothing that a pill that cools down headaches and fever, some rest and a towell wet with cold water wouldn't work.
Even if you still have 38,0°C, still fever, not high, but still fever, drink a lot of water, because your body is trying to regulate the temperature with the water you have inside, +, + heat, + sweat=water+salts, so less water in your body, that's why you're Thirsty (or something like that). Still, again, drink a lot of water, rest, put a towell with wet cold water in your forehead to drop a littel the temperature and to soften a littel headaches if you have, and take the fever Pills regulary and in the right time. At least in Portugal, we can only take another med for fever/headaches in 6-6 hours
