I found a more complete medical
based description of my condition.
I have an
Acromicioclavicular (AC) Joint Injury
The big question I have is whether this was a dramatic injury caused by a recent bike fall or long term condition caused by scrapping the boat
overhead for ten years.
The fact I am in no pain and have full range of motion leads me to believe this was long term injury versus dramatic injury after I suffered a bike fall.
"An overuse AC joint injury occurs over time as repeated, excessive stress is placed on the joint. Cartilage at the ends of the acromion and clavicle bones protects the joint from daily wear and tear. Over time, the demand placed on this cartilage may be more than it is capable of enduring, resulting in an overuse injury. Significant wearing of the cartilage is known as arthritis. Overuse AC joint injury is most common in individuals who perform tasks, such as heavy weight lifting (bench and military presses), or jobs that require physical labor with the arms stretched over the head
I am hoping if other long term sailors did or didn't also have AC joint injuries to narrow down the cause of my condition.
I am hoping also to avoid a non surgical treatment or may very well have to live with the condition as is.
