In my free time I’m a very keen sailor, but sailing can cause serious shoulder injuries.

Sailing has caused many sailors to develop acromioclavicular joint arthritis in their shoulders.  This is a specialized type of arthritis which develops as the cartilage located between the shoulder blade, collarbone, and acromion wears away.  The principal cause for this type of arthritis is overuse.

There are many shoulder treatment options, including shoulder surgery so do get professional advice as soon as possible.
