I did a lot of research whilst I was having a horrible time immobilized by the flu and you basically have to wait it out with painkillers and anti inflammatory drugs like ibuprofen and cocodamol until it’s gone.

I found some interesting information about how to prevent it (aside from a jab) and that is to spend more time outside in general. A study found that far less people who were out door workers contracted the illness compared to people who work in warm offices all the time. This is because their immune systems are toughened up with the instillation of the elements.

Well presented article though
