I was operated on just 2 weeks ago for DP. It had worsened to the point that I could not put gloves on and could barely place my hand in my pocket or grab a jar off the shelf. At no point was the condition painful, just a bit debilitating. It never impacted my cycling. My condition was advanced as the ring and pinky finger almost touched my palm. This made for an operation of 2+ hours and lots of stitches across the palm and up each finger. I too was told to watch and wait 3 years back by an Orthopedist, wish I'd gone to see a hand specialist earlier. It went from manageable to needing to do something about it quicly for me . Fingers are straight now and PT is easy as you can sit in a chair and stretch the fingers as now I need to work on bending them (the irony). Its not real serious, but still no fun and it'll likely be 4-6 weeks total for the hand to be functioning well maybe a bit longer for 100%. Cycling is out for now.
So, keep an eye on it.
