• Shoulder Bursitis
Shoulder Bursitis is the most common cause of shoulder pain
Bursitis of the shoulder essentially involves a structure that sits on top of the rotator cuff protecting it from the bone above called the acromion. Frequently, people develop bursitis in their shoulder and have classic symptoms of decreased range of motion and pain at rest and have especially a hard time getting to sleep at night for it is hard to move your arm to pull up the covers or put it underneath the pillow.
These cases are easily diagnosed with ultrasound technique and quite frequently, a simply cortisone injection into the bursa can be extremely beneficial. In some cases, you can use the injection needle while you are watching it to perform a technique called hydrodissection where the bursa is lifted off the rotator cuff and the needle sweeps back and forth like a windshield wiper, eliminating adhesions.
