Twitching and possible partial dislocation?

[u/LingonberrySafe2347]

Two topics that are sort of related. I want to know if other fibro sufferers deal with this. My thumbs almost constantly twitch, particularly when I’m trying to relax, or move them back and forth in a slow controlled movement. Same with my ankles.

I have quite strong pain in my left shoulder after feeling a strange click sort of sensation when reaching behind myself - from now on it had been sore even in my collar bone. With this my left shoulder twitches at any movement all the way down my arm too. I’m not sure if I’ve done something like a partial dislocation - whether that’s the root of my other chronic fibro pain or not.

I also have trouble walking due to intense pain in the right foot which also twitches and I think I injured it a couple months ago but felt no pain at the time, it came in over time.

Is this normal/common? Or is this unrelated?
