On Monday evening, I got bit by something in my sweats. It felt like I got jabbed by a sticker. When I got home, I had a bite surrounded by red. The red faded and the bite turned skin color after a while. It bothered me a little the next evening, but I didn't look at it. Yesterday morning at about 4 am, i woke up with a raging headache and high fever/chills. Tylonol wouldn't relieve either. The bite spot had developed into a red welt the size of a quarter. Later in the day, my face, chest and torso were covered in a rash. I went to bed early, and I feel quite a bit better today, but the welt is bigger and redness is spreading away from it. From what I can tell, it's most likely a hobo spider bite.
