<s>[INST] I think I was bit by a spider or a tick. I live in Michigan and have been cleaning my garage. I ve been sleeping in the garage too for about six weeks. I woke up early thursday morning with severe elbow pain- burning and tenderness. Within a couple hours I had a large blister on my elbow. Within 24 hours the blister had popped and came back three times and by then I had an off/on fever, infected eyes , muscle/joint pain and weakness, and my elbow has been very red and swollen ever since.
