Anyone who’s known me for any length of time will know that I’ve never been able to straighten either of my little fingers. My sister (the youngest sibling) and I (the eldest) both have the same issue, although it skipped our brother completely.
It’s not painful, and - with the exception of precluding me from a career as a guitarist - it’s never really interfered with daily life, but I’ve done some research on the condition several times over the years.
I’m reasonably convinced (self-diagnosed) it’s Dupuytren’s Contracture, or “the curse of the MacCrimmons” as the Scotts have referred to the flexed fingers of adult male bagpipers since the 15th century.
I’ve found a perverse pride in my assumed Viking heritage, but none so much as today when I discovered the “International Dupuytren Society" whose logo is basically "The Shocker”!
