So, it turns out that I had no infection-- they took blood cultures from three different spots (port and both arms), urine, throat, and X-rays and NOTHING. My fever was probably caused by a minor virus, but my blood levels all look good so they're not too worried about it.
The WEIRD thing is that my blood showed that I was having a severe allergic reaction. The doctor is pretty sure that all of my cold-like symptoms are because of that. And the best guess is the cat allergy since both times I was around cats, I got sick like this. It's weird that an allergic reaction could last 4 days (and get progressively worse), but they think my immune system is out of whack because of the chemo. I have been forbidden from going anywhere near cats for the remainder of my chemo (I think this means I am going back to the allergist). That means I can't go to my in-laws' apartment, and I can't go to Bible study. Goodbye to my whole support system-- I basically cannot leave my house.
I hate cats. Thanks for screwing up my life. I just have to hope that it goes away after chemo.
I also have a sneaking suspicion that something in my own house is contributing as I continued to get worse the last day or two. Dust maybe? I know I have a dust allergy, but it's never been much of an issue-- but maybe it's going crazy too!
