Final answer:
Lateral shoulder pain aggravated by abduction and external rotation refers to pain in the shoulder area that increases when the arm is lifted away from the body or rotated outwards. This is often indicative of shoulder conditions such as rotator cuff injuries.
Explanation:
The phrase 'lateral shoulder pain aggravated by abduction and external rotation' denotes discomfort on the external part of the shoulder that worsens when the arm is lifted away from the body (abduction) and turned outward (external rotation). This pain could be indicative of various shoulder conditions, most likely, rotator cuff injuries. These injuries occur when pressure or strain is placed on the shoulder's rotator cuff, a group of muscles and tendons safeguarding the shoulder joint.
Abduction and external rotation of the arm tend to stress this area, often exacerbating any existing pain. The understanding and diagnosis of this condition usually involves clinical evaluation and imaging tests like x-rays or MRI (Magnetic Resonance Imaging).
