Polymyalgia rheumatica (PMR) is an inflammatory disorder that predominantly affects individuals over the age of 50, leading to muscle stiffness and pain, especially in the shoulders and hips. Understanding its symptoms is crucial for early diagnosis and effective management.
Shoulder Pain
One of the hallmark symptoms of PMR is aching shoulder pain, often experienced on both sides of the body. This discomfort can make daily activities, such as dressing or reaching overhead, challenging. The pain may intensify at night, disrupting sleep, and can extend into the upper arms, resulting in a persistent, deep ache.
Pain in Other Muscle Groups
Beyond the shoulders, PMR can cause pain in other major muscle groups, including the neck, buttocks, thighs, hips, and upper arms. This widespread aching can hinder movements like sitting, bending, or rising from a seated position. The discomfort often worsens after repetitive movements or prolonged inactivity.
Morning Stiffness
A significant symptom of PMR is pronounced stiffness, particularly in the mornings or after periods of inactivity. Patients often describe a sensation of their muscles “locking up” upon waking, with stiffness lasting more than an hour. Sitting in the same position for extended periods can also lead to stiffness, making movement uncomfortable.
Limited Range of Motion
If left untreated, the stiffness associated with PMR can lead to a reduced range of motion. For instance, shoulder pain may limit the ability to raise or extend the arms, while hip discomfort can make activities like standing up or climbing stairs difficult. To avoid pain, individuals might unconsciously restrict their movements, potentially leading to further muscle weakness and decreased flexibility.
