My youngest is 25 yrs of age, usually pretty fit, works hard on the docks for an animal feed company, he reckons it started out as flu, he was rough the other day, visited the docs who said it was
"okay, just a little infection, take these (antibiotics) you'll be fine"

it got worse, he has all kinds of needles attached to him and had one entered in his back.
Thanks for yer thoughts tho'

I had a dose of flu two years ago round the xmas time, should have had a few days off work but they needed me in, after New Years Day I had some time off but it got worse and I ended up being taken in.
So get it sorted right away folks, it could turn nasty, even for a fit person.
