First off, I’m not asking for advice on what to do about my bone spur. I am curious as to how I aquired it.
The spur is visible through the skin, on the inside of my left wrist. I believe it to have formed on the point of my Radius. It is large enough that I would not be able to wear a watch on my left wrist, if I were so inclined (I’ve always worn it on my right, although I’m right-handed)
About 15 years ago I had a fracture in this same general location.
I did not trip, fall, or otherwise impact my wrist.
It formed during a time when I was doing a fair amount – 2-4 hours daily) of physical labor including: shoveling, lifting (not more than 30#), scooping, and pouring. No hammering or other impact-type labor (due to tennis elbow, I avoid this type of work).
As mentioned I am right-handed.
I am prone to tendon injuries due to hyperflexibility in my arm joints, including my wrist (established by medical evaluation, not my own opinion)
Any thoughts on what caused this spur to form?
