Polymyalgia Rheumatica

Polymyalgia rheumatica (PMR) is an autoimmune disorder that causes muscle stiffness and pain, primarily in the neck, shoulders, and hips. These symptoms often appear suddenly, sometimes overnight, and tend to be worse in the mornings or after periods of inactivity.

Other symptoms of PMR can include fatigue, unexplained weight loss, and low-grade fever. This condition typically affects individuals over the age of 50 and is slightly more common in women. The exact cause of PMR is unknown.

PMR shares similarities with another condition known as giant cell arteritis (GCA), which involves inflammation of blood vessels, particularly the arteries in the head and neck. These conditions can sometimes occur together. The most common symptom of GCA is a new headache, usually in the temples. Other symptoms may include scalp pain, jaw discomfort, unexplained weight loss, and vision changes.

Diagnosing PMR and GCA requires a thorough review of symptoms, physical examinations, and blood tests. If GCA is suspected, additional tests may be necessary to prevent serious health complications.
