Hi Pascal,
Yes, I had identified areas of atrophy in my wrist already around the time I had the emg. It's obvious to me, as is being weaker on the left, but no impressive clinical weakness during the office exam, he commented my pinky was a little weaker than the right. I have slender wrists both sides, but it's obvious to me the change that's occured sometime in the last year by my left wrist.
My left leg is about the same post-surgery. I still have weakness in my last 2 toes and can't walk on my heel on that side. And crazy muscle twitching. No progression though, so yay! I knew going in that nerve damage may be permanent, or worse, not caused by spinal issues. Just hard to tease out what caused what. What the surgery did help was chronic back pain. Mostly gone! It did help some angry burning pain around my foot & replaced it with numbness.
My emg/ncs is in 2 wks. 2 very long weeks

Just keep swimming...
