big pun-- glad to hear you're giving the treatment a shot. A bit of advice... give the treatment some time. I felt MUCH better immediately after my first treatment. I went back in for about 2 or 3 more, and continued to progress. But, as Dr. Leahy has pointed out to me before, you have to continue "working" the joint back into proper shape. After my last treatment, I still had about 3 weeks of working through some minor pain until the shoulder settled in nicely. The key is to pay attention to your strength... if its improving DURING your workout, then the treatment is working. My shoulders would still hurt at the beginning of my workout, but they felt better at the end after they were warmed up and used.
On a side note, El Cubano is incorrect in his statements about having a separated vs. dislocated shoulder. These two terms have absolutely nothing to do with severity or whether the joint popped back in. A "separated" shoulder really has nothing to do with your shoulder per se. It affects the acromonial clavicular (AC) joint. For those not familiar with anatomy, it is the joint located at the outermost portion of the collar bone, right where the trapezius ends. There are actually three different ligaments in the AC joint which connect the shoulder blade to the collar bone. Damage to any one of them constitutes a "separated" shoulder (there are three degrees of severity).
On the other hand, a dislocated shoulder is damage to the actual shoulder joint (rotator cuff, labrum, etc). A dislocated shoulder also has degrees of severity, but is in general a much more serious injury than a separated shoulder, as it affects a much more complex joint.
