The surgeon told me the shots were worthless as you have stated. Unfortunately dupuytrens comes back I think I can hold out a few more years before more surgeries and I am sick of it. I had dupuytrens in my left foot it is called planters fibromatosis that was no fun couldn’t walk for a few months but I had a scooter to scoot around on. But like everything you can overcome it and manage to ride bikes and do other athletic endeavors by just being determined.
