Type of disease: Rare conditions
Rhizomelic pseudopolyarthritis also known as polymyalgia rheumatica is an inflammatory disorder that causes muscle pain and stiffness, usually in the upper arms, neck, buttocks and thighs. Symptoms tend to come on quickly, within two weeks and are most severe in the morning. The average age at onset of symptoms is 70, and rarely does the disease affect people younger than 50 years old. Anti-inflammatory drugs called corticosteroids help improve symptoms, but careful monitoring is required for serious side effects.
Women are affected twice as commonly as men, and Caucasians are affected more frequently than other racial groups.
Polymyalgia rheumatica is related to another inflammatory disorder called giant cell arteritis, which can cause headaches, vision difficulties, jaw pain and other symptoms. It’s possible to have both of these conditions together.
