Like many of you, I had tried Vitamin E, Verapamil,massage,

Dupuytren's forms bands of elastic tissue that pull the fingers toward the palm - It is a mechanical problem.
During NA you can hear these bands break and see the finger straighten out.
The procedure is quick and easy almost without discomfort and results border on miraculous.
