I understand Dr Google, when what it says hits to close to home it feels like an actual punch in the gut. I have vivid dreams with recall, but not sure I do too much moving etc. My last sleep study didn’t show it, but if you don’t have an episode during the study, I’m guessing it can’t dx it, but that doesn’t mean you don’t have it. I’m 20 years older than you, so when I see folks in their 50s (some even 40s) being dxed with PD or MSA, it aches my heart. I will pray that your RSD does not progress to anything else. And, again, they are working on these things, it’s just a matter of if they can make the connection that will prevent, reverse and cure these horrible diseases.
