I've never heard of a herx before. What exactly is it?

This phenomenon is known as the Jarisch-Herxheimer Reaction (JHR) and is often referred to informally as Herx. JHR is believed to be caused when injured or dead bacteria release their endotoxins into blood and tissues faster than the body can comfortably handle it.
