Let's take a look at what is so special about the shoulder anatomy for the biceps. Here are images that will help you understand what makes this different than your normal "itis" treatment. The first view is a highlighted isolation shot of the biceps tendon and attached muscle. As the muscle turns to tendon you can see it travel up into the bicipital groove, passing below the transverse humeral ligament and into the shoulder where it attaches at the supra-glenoid tubrical. The second image is what is really interesting. That same anatomy shot from above gives you a clear idea that this is not just about swelling from overloading, but also about space and angles. If that tendon becomes so inflamed that it cannot in fact pass easily through the "tunnel" formed by the anatomy, it will friction along it, which in turn creates more inflammation. There are 3 factors at play here which can be directly effected by massage, the width of the tendon passing through (is it irritated?), the health of the ligament (is it swollen from repeated impact and abuse) and the angle at which the tendon passes through the "tunnel" (which can effect both the tendons inflammation and the ligaments) Your intake should help you decide what the aggravating factors are, and there by the main problem, which might be 1 or all of the contributing factors.
