Sounds like you have had a rough times with your hands.
Early this spring I had numbness in my fingers when I woke up but this was during a flair that was attacking the lower part of my C-spine. So I wrote it off as a side effect. In my original post I wrote “about a week ago” this started – I meant to say ‘a month ago’
The contrast baths actually sound like a welcome relief – I will try that tonight. And I was just trying to cut back on my muscle relaxers, but maybe that was a bad idea.
Your torn ligaments sound a little scary.
