Physical manifestation of RSI?

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?

 

Update after 5 minutes of googling:

Apparently it's quite normal. I'm quite relieved.

Hi, Baru.
To fight pain with TMS I like to use one of my fingers. The middle one on my right hand.
I stick it straight up into the air.

 

"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."

Same thing with me, but I don't have RSI. See above that it's quite normal as you state. No problem. No pain.
