I've just had radiotherapy for stage N dupuytrens contracture. Talked to a lot of others I. The waiting room. IME, and from what they said, it doesn't hurt. It itches, like made, but it doesn't hurt,
First noticed it in my knuckles and then the palmar fascia started to thicken over the little finger and ring finger. It develops next as a small squishy lump which doctors tend to mistake for a ganglion cyst, but it starts to grow a "tail" along the tendon as a cord forms.
The one thing I've not experienced it doing is hurting. It can be uncomfortable and itchy, but mine never hurt. Well, not until I had it nuked with X-rays.
