Hi Hal. We messaged last June..my dad has flail arm. I hope you are doing well and managing. I wanted to ask you if you experience neck stiffness? Dad is having muscle stiffness in neck for a few weeks. It could be related to doing things awkwardly, we just arent too sure. Its not weak, just sore/stiff. No other changes, arms maybe a bit weaker. Take good care.
Yes, although very subtle and mostly only in cold weather, I first experienced issues with my fingers in late 2019. And while I've lost a great deal of muscle mass in my arms and shoulders over the last year, I still have good range of motion and per my PT person, my leg and core strength are still in the 95% for a person my age.
