Restless Arm Syndrome

Some weeks ago, as I was lying on my couch and undertaking my age old stress management of eternal scrolling and listening to murder / accidents / plane crash investigations, when my left arm twitched. It crept up on me. What I can only describe as a burning anxiety set in to my shoulder and upper arm. It went away for a few brief seconds when I moved my arm or tensed the muscle, but otherwise it just sat there, fat and heavy, destroying all my attempts at relaxation.

At first it was only there when I was incredibly relaxed. I’d begin my relaxation routine, and it was only when I was well and truly relaxed, body pliable and muscles limp, that it would come.

Then it came as I was relaxing. Then it came whenever I just lay down and stopped for a few minutes.

It was at that point that I really started to notice it and pay attention and catalogue it. It felt like a bad case of anxiety energy – that one you get where you have burning need to do something, anything but you can’t make yourself do a damn thing, so it sits in your chest and tightens until you want to explode. My shoulder and upper arm muscles spasmed more frequently, and the only relief I got was from moving my arm. It didn’t matter what position it was in, once it stopped moving, the burning sensation came back. I tried to google “anxiety in my arm” which, understandably, didn’t produce many results. I kept digging and came across Restless Arm Syndrome. I’d only ever heard of Restless Leg Syndrome, which is a common enough comorbidity to Fibromyalgia.

Restless Arm Syndrome is typically where Restless Leg Syndrome progresses to. When it’s really bad, it can involve more areas of your body than just your legs. But I’ve never had this feeling in my legs before, and no other body part has ever been involved, so it couldn’t be that, and I really struggled to find any information on primary Restless Arm Syndrome.

Regardless I went to see my GP who advised that, fortunately, the treatment for Restless <Insert Limb Here> Syndrome was pregabalin. The pregabalin that I’d just finished weaning down from 300mg twice a day to 150mg twice a day. As soon as I’d increased my dose back up to 300mg twice a day, however, the arm stopped burning and twitching.

I think it may be creeping back in lately – there are a lot of unavoidable stressors in my life at the moment, which could be contributing to it – but it is still considerably better than it was. I’d love to be on less pregabalin, it makes me feel emotionally flat, but I really like not having anxiety arm!
