I've had it for about five years, first in the right hand and more recently in the left. Last year I started going out with a holistic healer. She recommended drinking pineapple juice regularly (the juice is used to tenderise meat so may help with the contracting fibres in the tendon sheath).

After a year of drinking about half a pint every day, the decline appears to have stopped. I've no idea whether it will help my hands get better, but I'm hopeful.

I should also add that I haven't eaten meat in 30 years, which may also have helped slow down the condition in the first place.
