You'll probably get lots of replies from people more knowledgeable and experienced than I am, but the symptoms do resemble the ones that I started having in the spring. The idea of a food poisoning "trigger" doesn't relate to my situation, and I hope someone else will comment on that. (My own "trigger" remains mysterious, but it may be the fractures in knee and shoulder that I got from a fall about 6 weeks earlier.) But what doctors has your daughter consulted? Has anyone suggested an EMG (electromyogram) and nerve conduction study? That's what led to my diagnosis of peripheral neuropathy. (The cause of THAT is still unknown. But there ARE treatments!)
