Self-diagnosis and the shoulder

OK, more shoulder injury information, mostly because it beats working...

The shoulder joint is formed across three major bones: the humerus, the scapula, and the clavicle. Four muscles that hold the free floating humerus to the scapula comprise the rotator cuff: supraspinatus, infraspinatus, teres minor, and subscapularis. Like many people, I often whine about an 'old rotator cuff tear' but now that I've thought about it a little more closely, I think it's more likely I have a chronic (read: often reinjured due to stupidity) shoulder separation.

A shoulder separation is a disruption of the connection between the scapula and clavicle, which occurs primarily at the acromoclavicular joint, where the end of the clavicle approaches a fingerlike projection off the scapula called the acromion process. The clavicle has additional connections with the coracoid process of the scapula. Shoulder separation comes in three main flavors:
- Type I: a sprain (partial tear) of either the acromoclavicular (AC) or coracoclavicular (CC) ligament
- Type II: a complete tear of the AC ligament, +/- partial tear of the CC, some shoulder displacement
- Type III: complete tear of both AC and CC ligaments, severe shoulder displacement

What I have is point tenderness over the AC joint, and a general worsening of the tenderness after exercises that put a downward stress on the shoulder (OHS, heavy DLs, etc - for example the heavy triples we did a few days ago). Not really too much to do about it, I think, except to keep the NSAIDs on after acute aggravation and being careful with the weights - no surgery needed (yet)...
