I can't be 100% sure, but I think I have been the victim of a black widow bite. It must have been hiding in one of my shoes. I put it on and felt a discomfort like there was a pebble inside. I shook it out and didn't think twice. A couple of hours later my foot started hurting. I figured it was just an irritation of some sort. I cooked dinner but didn't really feel all that much like eating. While sitting on the patio with Kitty I just felt drained of energy. I decided to go to bed at 8:30. The next day my foot was still bothering me. Once again I had no appetite for breakfast. At work I was sitting at my desk when I started shivering uncontrollably. I cranked up my space heater and huddled around it. Soon I was too hot like with a fever. Lunch time approached and I still didn't feel like eating. I decided to call it a day and head over to urgent care. They couldn't do much for me. The symptoms were textbook for a black widow bite but since I didn't see the little bitch I can't be 100% sure. Rather than go to the emergency room for anti-venom, I just decided to ride out the symptoms. Basically I just crawled into bed and slept for about 14 hours.
