Hello Jane. I have Dupuytren's contracture (as does my father). It's supposed to show Viking ancestry!
I had an operation in Brittany on my left hand in 2002 for the tendon to my little finger. This was successful, but then a few years later it started on the next finger along. I was referred to the CHU hospital in Caen (different département), who told me that I was too young for an operation (at 40) and told me to come back only if it became painful and/or debilitating.
It's funny you should mention Reiki, as I have a friend who is a Reiki master and when I asked if she could do anything about my hand, she took a look and gave me treatment. Strangely, she seemed to connect it to my feet, so treated them too. I had suffered from foot pain too. I was absolutely amazed as it looked to me to have made a physical difference to the appearance of my hand. Without saying anything to my husband, I asked him if he had noticed anything about my hand and he picked up on it straight away.
That was about 5 years ago and my hand has not changed since. It spurred me on to do a course in Reiki myself and I often treat my hand. I have also not had the foot pain since.
Here's a little story too - not long after my operation we went on holiday, driving down from Brittany to Spain. This was, and still is, our only holiday (apart from skiing in the Alps each winter) since moving to France in 2000. We planned to stop in Limoges and find a cheap hotel, but everything was fully booked. so we continued down the motorway and spotted a sign for a "ville étape" with hotel and shops. so we spent the night there. In the morning, when we came out, we discovered that the hotel was next to a pharmacy, Pharmacie Dupuytren and opposite was a statue of the man himself. It was his home town! Serendipity?
