Burning up...

I woke up from a nap yesterday with a low grade fever yesterday afternoon.  My temp is lower this morning 99.1, but high for me...Normally I wake up at 97. something...and there's a little fluctuation, but I'm never normally 99.anything.  I've read up on the subject and from what I saw...it's not really a cause for panic unless my temp reaches 101 or over.  I don't know whether it's the seasons, the medication switches or what.  I know being ill when it's warm out makes me twice as miserable.  It was 80 degrees out yesterday.
