I agree with all of you who decided that the treatment available in the UK for DC is really very biased and limited. Why can we not learn from other countries? RT in Germany is quite common and well researched, the same is true for NA in France etc. At least the medical establishment in the UK is now accepting NA, but RT is still frowned upon.
When I discovered that I had DC 18 years ago, aged 48, with a strong family history, I still trusted the advice I was given and waited until my finger contracted 9 years later for an operation. I have to say that this has been quite successful, but I was very incapacitated in the use of my finger shortly before the op. Also, a full anaesthetic and a day in hospital with a lot of hand exercises afterwards were all quite unpleasant.
As I also had an index finger on the same hand which already had quite a lot of nodules and chords and had contracted about 10 degrees, I did some research on my own and discovered the availability of RT in Germany for this finger. At the time, the consultant thought that it might already be rather late and sure enough, after an initial improvement DC recurred and my finger had contracted again 6 years later. This time, I was treated by NA in Brussels and was delighted with its painlessness, simplicity and the result. Sadly, at present, contracture is happening again, but I am determined to simply go for another NA treatment with this finger when necessary.
In the meantime, however, I had discovered a new third small nodule in my other hand and by sheer coincidence talked to my chiropracter about all this. She suggested that I try ultrasound and to my delight, I found that it softened this nodule almost immediately. I have continued regularly treating this finger over the last 9 years and the size of the nodule has gradually reduced. I also have no contracture as yet, in contrast to my previous 2 fingers which over a similar time period had contracted to about 90 degrees!
However, as for RT, there seems to be a short initial period where ultrasound treatment is effective.
So my advice is not to wait! Go for RT or if you want to see if ultrasound works for you, give that a go. Just a basic machine should do it, I have treated myself 2-3 times a day for 5 minutes. It is safe with no known side effects, it just takes a little time. But act during this early phase, don't wait!
