I have had numbness in my hands and feet for years but a few years ago I had a numb buttock and thigh. I ignored it. 2 days later I woke up with the left side of my face all numb. Panicked. Went to my GP convinced I'd had a stroke. No. It's my fibro. It still affects all of my left side. It's more of a lack of sensation than numbness these days luckily.

I haven't had it for that long that I remember, but I do have numbness randomly (I used to get funny looks when I told people my knee was asleep). It's quite annoying.

Raynaud’s? It doesn’t have to be cold at all to experience the symptoms.

All these things are scary, I've felt this too and thought something was really wrong

Constantly. I've found keeping hotpads on my feet to help push different nerve reaction away from numbness. I also sleep with my head angled up like a fully reclined chair with that slight tilt. As long as my hands are below my head and heart it seems to help a lot. I also use good thick lotion and massage areas that are common problems. Doesn't always work, but I kind of try confusing my nerves away from their over reaction. (If that makes sense) Best Wishes for a better tomorrow. :)
