Hi Pat, welcome to Connect. It’s not uncommon for people with CLL or any blood cancer to have fever and chills, night sweats/chills. I had another form of leukemia and could not get warm sometimes. I often wished I had a blanket warmer like hospitals! 😁 Second best was just tossing throws in a hot dryer, then wrapping up for a while. Sipping hot tea, coffer or even hot water really helps heat up from the inside.
Is your red blood count normal? Anemia can be a cause of chills.

I’m posting a couple of links below for discussions with other members who also have CLL. More can be found by typing in CLL in the search window at the top of the page. The search will bring up a list of all the chats.

What has your doctor discussed with you about the mass in your uterus? Is this a fibroid that will require surgery?
