Dr can't figure it out ... thoughts?

[Raven]

I got asked
and i'll NEVER do it Again
to drive a Sick co-worker home...
he looked ghostly white and sick as a dog
why he came to work like that is anyone's Guess

Later that evening i started a fever and
had the shakes so bad it was as if i was a
paint can in a shaker/mixer...

i laid down (collapsed) in the shower shaking uncontrollably
still dressed for an hour and eventually had to sleep it off
for days without any of the normal flu symptoms you
experience feeling like i was gonna DIE.

it weakened me badly and i had every bone hurting like the devil.

it was some form of influenza i was told and that is why
i suggested to treat it as a flu BUG.
