As I posted back in 2005, I had all the symptoms of Lymes, was constantly feeling run down but had tested negative for Lymes.
Continued to feel like this for another 5 years and finally gave up on NHS, went private and was diagnosed with severe toxaplasmosis and gluten intolerance. Probably got the toxaplasmosis from living in France. Normally harmless but my immune system was severely compromised by the underlying gluten intolerance.
Having those private tests literally turned my life around.
Couldn’t recommend private tests highly enough if you can afford it.
