Brilliant that you finally have a confirmed diagnosis. It must feel like it’s been one hell of a journey.
Now you can get some tools to help with symptoms. I’m sure you already have (I probably gave you) this link: What Is FND - FND Hope International Maybe it’ll help?
Don’t feel like you don’t have MS so you can’t come back on here. We’ve been your support group for a while, and you’ve been just as supportive to others. So if we can help, just ask.
I noticed that one of your symptoms you were dealing with was numbness in your fingers and legs on waking up in the morning. That most usually is caused by sleeping in an awkward position and reducing the blood supply. If you wake up and find your fingers /arms / legs numb then take a moment to consider how you are actually lying, to see if it may simply be caused by this. Having your arm tucked under your chin (which many of us do) is often the reason for the numbness in the hands and arms. Legs too can be due to leg position.
I get this and have been training myself to sleep in a different position. It takes time, especially if you’ve slept that way for years!
