I had a crazy idea. I have ME/CFS triggered by a lyme infection. The lyme infection appears to be long gone but my symptoms are not. I had the crazy idea that what if I were to get infected with Lyme disease again, treated with antibiotics after a few days or so, and see if my immune system remembers this time to switch off. It might be the same immune regions that activate fully to fight the infection so activating them fully again might mean they remember to completely switch off, rather than only partially switch off, which is what they (the immune regions) seem to have done. Any thoughts on this idea?
