Two days after returning from a weekend hunting trip, Maggie notices three sting-like piercings on her lower left leg. Because she has been on such hunting adventures for many years of her life, and is used to bites from different insects, arachnids etc, she ignores the marks. After being back for almost two weeks, she experiences mild joint pain and difficulty remembering things, but hesitates to go to a hospital. On the 27th day after her return, she wakes up at night with a severe headache and neck stiffness; while she is almost about to turn off the bathroom light and return to bed, she notices a bull's-eye looking rash, on the superior portion of the back of her shoulder, as she walks past the mirrors.
