Tonight as I’ve been trying to sleep I keep feeling a bubbling feeling in my right calf. It feels like something is tingling and bubbling so I have to move my leg to get it to stop. I looked it up and RSL came up, and I am now frightened as to what exactly is causing this. Does anyone else have this? If is just a really weird feeling and it’s like bubbling. Is restless leg syndrome dangerous? I can’t sleep now it’s constant.
