Congrats on getting in to see a specialist soon!
Yes, fevers are common with Lyme, so is a lowered body temp.
You should also ask your doc about
thyroid and adrenal issues, as those will cause body temp fluctuations as well. Lots of us with Lyme also have thyroid and adrenal issues as well.
One site to help you learn about
your thyroid and adrenal glands is
www.stopthethyroidmadness.com There's lots of good information there!
In the "New to Lyme?" thread is a really great 'master symptom list' for Lyme disease that can show you most of the symptoms of Lyme Disease. While you are there, you should also check out the symptom lists for the other tick-borne infections as well, since Lyme rarely travels by itself.
