What is a Herx?

A Jarisch-Herxheimer Reaction (often called a Herx for short) is the reaction that your body gets when there is a spike in die offs from the Lyme disease and associated co-infection bacteria.

It is sometimes seen as a good sign (that the medication is working), however severe Herxes can be dangerous (causing brain and organ damaged) and so need to be managed carefully.  As such, the LDAA recommends you work with an experienced Lyme Disease doctor to guide your treatment, rather than self treating from information that you have sourced off the internet.
