Feels like I'm not in control of my arm.

The last couple of days I've been experiencing something really weird and it's really eating my head.

I've complestly lost my release, before it was just an instinct. Didn't even think about it. But it started that I "forgot" to release the dart. Not completely but darts aimed at T20 ended up at the lower segments of the board and sitting at weird angles. Obv I knew myself that it was released late. This kept on going until I tried to release the dart earlier which also made things very awkward. After all it still just feels like I've lost the control over my arm. That I'm not the one in charge. It maybe sounds ridiculous but thats the way it feels. Before I had full control, if I threw a poor dart I knew it was my fault. Now the darts are going all over the place. Just like when someone is throwing for the first time.

But now it just feels like I can't do anything. I need to say that my arm in general feels a bit off. Also my elbow feels kinda off.. maybe it's just a cope from my side

What should I do to battle this?? Surely someone has experienced the same.
