I've been 'suffering' with RSI in my hands, arms and upper back for a while now. And while I understand TMS well, there's still one thing that keeps seeding doubts in my head. When I try to flex my pinky finger on my right hand, I can't do it without also flexing the ring finger. And in the last 6 months or so, my middle finger also flexes slightly when I try to do the motion. Meanwhile in my left hand, I can flex each finger individually. Before I knew about TMS, I would attribute this to nerve damage or something, but now, I don't know what to think. Is this normal? What the hell?
