I suffered with restless leg syndrome a while back. Wasn’t a pleasant experience. Screwed with my sleep for a while and got into my head too, as the feeling was odd and frustrating. I used to have to get out of bed and walk about and do some stretches.
No idea why it went, I didn’t figure out how to get rid of it. I partially thought it was in my head and by thinking about it I bought it on. But no idea if that was the case. I hope it doesn’t come back
Hope it disappears for you soon mate, it’s an annoying feeling
