I am not a doctor but I stayed at a Holiday Inn last night. Disclaimer: I do not endorse, sell, or recommend this to anyone else. I am simply stating something that has definately given me relief.
My Aunt, who has extemely bad arthritis recommended I try DMSO (Dimethyl Sulfoxide-a simple google search will give results) on my dupuytrens. She uses it and swears by it. A bottle of 99+% pure dmso cost about $10 and will last a LONGGGG time. I have early stage of dupuytrens and stretch my hands regularly. I started applying DMSO on my palms about a month ago and it definately is helping mine. The 'pulling' feeling during my stretching has greatly reduced and I believe that the nodules(I have 3 on the ring finger of each hand) are actually starting to shrink. How I got the disease, I'm not sure. I was never a heavy drinker, no family history, but I did take msm/gc for about a year and a half for knee problems.
Like I said, I'm not recomending this to anyone(there's that legal disclaimer again) but it sure is helping me.

Michael,

I was thinking of giving DMSO a try, until I read your response. Are you using it on your hands, or drinking it?

when I tried it my whole body started to smell like a big clove of garlic.
