Best wishes for a swift recovery Mick. You're not doing too badly so fingers crossed you'll have no problems.
Swine flu is not as scary as it has often been made out to be. The main worry was lack of existing immunities in humans, leading to a greater likelihood of pandemic status. But in terms of the range of severity it goes from about the same as a head cold all the way to fatal lung complications; which is also true of many strains of influenza.
