My step-dad had trigger finger surgery - he got a very good result - but he's not HMS or Ehlers-Danlos.
My doc just today is referring me to Orthopaedics for my most recent wrist dislocation - I asked why, and he says 'to see if there's surgical correction they think would be beneficial'. I certainly don't want to go down that road if it's not necessary. But perhaps the Orthopods will understand HMS/EDS a bit better than my GP.
I also agree with nonyanomemory about you working out how painful/disabling the trigger finger is for you. When I saw the doc about my knee, I asked how I would know when it was time for surgery. He said, the pain will tell you. eep! But it was good advice, because I know I'm not ready yet.
It's not just a body, it's an adventure!
