inflammation for 1 year?! is that possible?! Histologicsl studies have shown that the tendons of so called "tendonitis" conditions have no inflammatory markers within them. Pain is due to a complex mix of nociception, peripheral and central sensitvity............there is some evidence emerging related to soft tissue degeneration and links have been made diet causing chemical imbalances within the tendons and subsequent pain ( Do some research!...type in tendonopathy or tendon pain into medline).

Also how the hell did you diagnose that it is the supraspinatous tendon affected? remember we treat patterns of pain...NOT ANATOMY.........unless you have opened the patient up removed some of his SS tendon and performed a histological study on it you don't know what structure is involved!......all you know is he has shoulder pain.

Steer clear of ultrasound and mobs and get a bit more pro active in your assessment and treatment of the shoulder joint complex
