Thanks for posting that article, Mikie. Co-infections are much more common than the mainstream medical community leads people to believe.
I know many people with multiple tick-borne diseases. I even know one person who had 7 different infections at one time. Almost everyone I know with multiple tick-borne diseases, and I lead a Lyme support group, was not diagnosed by a conventional healthcare practitioner. They remained sick for months or years and sought help from a Lyme literate healthcare practitioner.
Yes, it really is very sad. The hardest part is that the cost is usually out-of-pocket when conventional "insurance" doctors can't help. That excludes many people from getting the proper diagnosis and treatment that they need.
