Just to give everyone an update: the prolotherapy treatments have stabilized my SCJs to the point where they no longer sublux with overhead motions.

I am currently writing a case report/lit. review with the doctor who treated me (I'm a premed student) and hope to have it published early next year.

I have documented a great deal of sternoclavicular joint research on my website:
The Forgotten Joint: Sternoclavicular Subluxation, Sternoclavicular Dislocation, Sternoclavicular Treament

It contains research on the SCJ, prolotherapy, my personal story, and a recovery blog.
