I injured it when I was holding a stray dog by the collar while someone else phoned the owner. He was a big dog, probably labradoodle, and very bouncy. He did a pirouette and his collar twisted around my hand/fingers. That was about 10 days ago. There was no obvious injury or bruise, and there's no pain when I move it, but mild pressure gives me pins and needles along the outside edge of my finger and firm pressure (like opening a jar or holding a full kettle) is very painful.
It is getting better but really slowly. Can I help it along in any way?
