Rashes

The original rash recognized as being associated with Lyme disease was called Erythema Migrans (EM), and was more commonly known as a bull's-eye rash. While this typical form of the rash may be most prevalent, or perhaps most recognized, it has since been discovered that the rash may assume other shapes and sizes. It usually will appear within a week to a month after a tick bite, and there can be multiple secondary rashes. In this section, we have included pictures of a few of the various rashes that have been found, but this selection is not all-inclusive.

The following are important points for you to remember concerning the rash:

* While the exact percentage of people who develop the rash is disputed, and ranges from 30% up, remember that not everyone who is infected with Lyme disease will develop the rash.
* The rash can be mistaken for other conditions; for example, dermatitis, ringworm, or spider or other insect bite.
* It is possible that the rash will go unnoticed.
* The EM rash is one of the symptoms accepted by the CDC as conclusive for Lyme disease.
* If you find a rash, seek medical attention immediately. Prompt treatment may avoid dissemination of the disease which could lead to chronic Lyme disease.
* Take photographs of the rash - it may disappear before it can be seen by someone able to discern whether it is a symptom of Lyme disease.
