Why didn't I develop a fever?

I'm currently recovering from tonsillitis which I had for a fortnight or so and which eventually resulted in a peritonsillar abscess (quinsy) which needed surgical drainage as it had swelled up so much.

Part of the reason it got so bad was that I did not realise that I was ill. Obviously, I knew that my throat was sore and that I felt a bit rough, but people have sore throats all the time. I kept putting it down to different things like hay fever, must have swallowed something hard which scratched my throat, etc. Besides all that, I was far too busy to be ill. It was only when I had lost my voice and my throat had swelled so that I could hardly breathe (which happened in the space of about 5 hours) I realised things were pretty serious.

Over the next couple of days, five different doctors examined me and all of them remarked that my temperature was normal or even slightly low. At the time I didn't really care, but the more I think about it, the more I'm wondering why I didn't have a high temperature. I had a serious bacterial infection - when they eventually drained the abscess, they released 10ml of pus (the doctor perfoming the op was seemed thrilled at the amount). I should have had some kind of fever at some point. And I would probably have taken the initial problem more seriously if I had had a fever, therefore stopping this nasty illness in its tracks before it ever got so bad.

Does anyone know of a reason why I did not develop a fever? Is it just one of those things that happens sometimes, or something to be aware of in the future if I feel ill again? Or even an underlying cause that may need to be looked at?
