My arm and hand (left) keep wobbling and shaking. I think it’s because I’ve got muscle wasting, which is because od my frozen shoulder…. If you watch a kestrel hovering it’s body is buffeted by the wind but its head stays still. My hand is not like that! My hand shakes and I stab at my phone keyboard. Half the time I miss and hit the wrong letters. This has got to get better. The tension in my shoulders is like the weight of the world…. Why do I have to hold it up?
