Thanks for this. I'm not in the least surprised. I'm willing to bet all sorts of infections via the gut, often via or in conjunction with gut dysbiosis, cause nerve damage and a host of other problems. We know so very little about all this, and we're just starting to learn. The traditional stool tests are not the best/most precise, but they can be useful in the case of a handful of known infections. I believe there are thorough stool analyses at labs that will even note bacterial and yeast makeup, but they are usually not covered from what I've heard and cost several hundred dollars. I think naturopaths and alternative physicians perform them.

Edit: Just to be clear, they do check for the particular infection you mention, but it often takes several samples, if done properly/thoroughly.
