There's a little-known reason why shoulder pain keeps coming back no matter what you try and most doctors never explain it.
That reason is something orthopedic specialists call Tissue Starvation.
Think of Tissue Starvation as "the silent killer of shoulder healing."
Under normal conditions, your shoulder is bathed in nutrient-rich blood that keeps the rotator cuff flexible, strong, and self-repairing.
It's a natural process and under normal conditions it keeps your shoulder pain-free and mobile.
The problem is that chronic shoulder pain has nothing to do with "normal conditions"...
Because once you hit 40, blood vessels in your shoulder begin to disappear. Flow drops by 30%. Then 50%. Then 70%.
Your rotator cuff starves for oxygen and nutrients.
And this is why your shoulder won't heal no matter how many cortisone shots you get or how much physical therapy you do.
