Yes, there are many rashes associated with Lyme Disease. The skin has been considered an "organ" by some and surely many of us have suffered w/rashes. There are also lesions that can be quite wicked and almost all of them itch.
I had a horrid rash on my neck and chest, it went away w/abx treatment. It also got me on the insides of my forearms. Another lymie, Kathy Boss, had rash as a major symptom. It was getting into her eyes and she was looking at blindness. She took a treatment out of the country that made the rash recede. They didn't question her leaving the country but returning they pulled her aside and asked if she was contagious. That is how bad a rash can be. Otherwise many don't experience it at all.
Type in Kathy Boss under searby by name and you can see her entries.
I hope you're ok w/rashes. I hear the Miracle II soaps can really clear them up.
Write me if you have any questions!
