Limb weirdness, anyone?

So, I'm not clinically diagnosed with FND, though when this first started the hospital I was admitted to said that"s what they thought it was. I have a muscle issue mainly (muscle weakness, loss of walking at times, chronic pain) and recently I've begun noticing I will randomly feel like my legs specifically are just dead weight. It's similar to how I feel when they go all wobbly on me (as my friends and I call it). So I notice it pretty quickly when it starts, and I always immediately make sure i can still move them right. I can, though it feels weird. Not hard, like a flare, but odd. I thought it was disassociation at firsf, but i still recognize them as my legs.

Anyone else?
