E.1.1 | Medical condition(s) being investigated |
Polymyalgia rheumatica
Polymyalgia rheumatica is an inflammatory rheumatic disease that occurs primarily in the elderly with a peak incidence around 70 years of age. It is clinically characterized by shoulder girdle and hip pain and stiffness which impair raising arms and rising from a chair. |
