Headaches usually come and go with the flu, and it is much the same story with roseola. Many medical professionals claim that the majority of headaches, with the exception of migraines, brain problems and those caused by impact, are simply caused by dehydration. People who regularly suffer from headaches might not be inclined to suspect they are due to an infection of the flu or roseola, however if their usual headache remedies, such as rest and drinking lots of water don’t’ serve to expel the headache, then it’s likely that one of the two is on its way.
The headaches suffered by fly patients tend to be felt in the sinuses as much as the head, and this is perhaps one subtle difference that patients with roseola may notice. It is a contrasting drop in an ocean of similarities though, and so having a guess might prove just as successful betting wise as trying to make any kind of informed judgment.
