Had a root canal yesterday which I thought would cure my issues of headache, low fever, chills, and general blah. I was up last night with chills worse than ever. My jaw hurt so much because I was shivering. I threw up all of the water I drank and I'm still not able to hold down anything. I have been having nightmares and night sweats for a while now but the chills are new this week. I called out of work for day 2 of doctor appointments and even though I feel like a hypochondriac because I hate calling in I am freaking out about what could be wrong.
