Sometimes what a person calls “chronic Lyme” isn’t actually anything, at least not anything pathological. I have very noticeable eye floaters (which any doctor will tell you are completely benign debris in the eye’s vitreous) and I have occasionally done a web search to learn more about how they arise, what they really look like, etc. But web searches for eye floaters these days tend to bring up a lot of people claiming that eye floaters are Lyme bacteria, or whatever, and having them is a sign of “chronic Lyme”.

In one forum thread I stumbled upon in the self-diagnosed “chronic Lyme“ community, people were claiming that eye floaters are "morgellons", i.e. the person must have chronic Lyme which in turn led to Morgellons syndrome. It was both of the imaginary diseases of the new millennium combined into one superstition!

You'll also see people touting gluten-free diets to help the symptoms of "Chronic Lyme Disease" and the theory that "Chronic Lyme Disease" causes "Non-Celiac Gluten Sensitivity" (google it for mind-numbing websites).
