Hi Georgia,
This will not eliminate Lyme or its co-ifections, but have you tried cutting nightshades out of your diet? Due to their solanine content, they act like neurotoxins on the body and often cause arthritic symptoms, even in individuals who don't have Lyme. I get arthritic pain in direct proportion to the amount of nightshades I eat. Here's a link with more information: http://www.noarthritis.com/
