Same here KitKat.
I wear a resting splint at night. It's a bit cumbersome, but easy to get used to. It has helped me a lot. Fingers still curling - but a whole lot less. That's my experience. I purchased from leeder group dot com. You can find it on line - it has fake but comfy sheepskin and is washable. About ninety-nine dollars. I do have a contracture, but I can still wear it . Please ensure you form fit it correctly. A palm is curved. I think there's a video on their site.
Massage can help - temporarily - in my case. Please make sure you massage from the finger tips towards the wrist. I was having it done incorrectly resulting in swelling of my fingers.
