During his car accident with the back window of the SUV, Zach is exposed to a species of Staphylococcus bacteria that at the time was living on the skin of his thigh. He develops no symptoms, and
two days after emergency surgery to repair his femoral artery, he is able to return home, where he enjoys hearty red-meat dinners for the next 3-4 evenings to celebrate surviving his brush with death while using a magnesium supplement to help him sleep at night so he can continue recovering. However, within a week of returning home, he begins to experience waves of excruciating pain from the middle of his lower back all the way around to his groin, and he notices both a reduced frequency of urination as well as the presence of blood in his urine. What exactly is happening to Blake? How has the confluence of his latent Staphylococcus
infection, his recent diet change, and his supplementation with magnesium led to this condition?
