In my case, the ulnar nerve in my R hand had a slight lump. And my pinky and ring finger all the way to my wrist has a numb feeling. No pain unless it was strained. Then the mass on my ulnar got bigger and instead of the numb feeling, it went to electricity when touched. Even the wind would hurt. Pain shoots from my hand to forearm to shoulder to neck. Like I threw my arm out. I have bone loss in some wrist bones. My hand is shrinking. Skin turned colour, hair grew faster, I shave it now for the lido patches. Nails grow fast. Wounds heal in weeks instead of days. My mind has been turning to mush. It's been about 10 months now since my accident. I didn't catch it early and that could have been my demise. I can still use it some so I'm grateful for that.
