Morning stiffness, unusual fatigue, or difficulty performing simple movements… These seemingly harmless symptoms may indicate a little-known inflammatory condition. Find out how to recognize the early signs of this rheumatic condition, which primarily affects older adults.
When the body sends warning signals
The first symptoms usually manifest as an uncomfortable sensation in the shoulders, as if an invisible burden were restricting your movement. This bilateral discomfort—affecting both sides of the body simultaneously—turns mundane actions like reaching for an object from a height or putting on a jacket into real challenges. The situation worsens during the night, when the discomfort can become so intense that it seriously disrupts sleep. Gradually, this pain sometimes radiates to the arms, creating muscle tension comparable to aches and pains that won’t go away.
A disorder that is not limited to the shoulders

The problem often extends beyond the shoulders. Many patients report dull aches that spread to the hips, thighs, buttocks, and sometimes even the neck. Everyday actions like getting up from a soft couch or picking something up from the floor become painful ordeals. The body seems to resist every movement, especially after a period of inactivity or upon waking. This sensation is reminiscent of post-workout soreness, except it persists indefinitely without improvement.
The difficult awakening: a revealing indicator
In the early morning, joints feel rusty, as if they require a long “thaw” period before functioning normally. This characteristic stiffness can persist for more than sixty minutes after waking. Some patients compare this sensation to muscles that have been frozen overnight. Although gentle stretches can provide temporary relief, without proper treatment, a gradual reduction in range of motion can occur.
Gradual loss of mobility

Over time, people instinctively develop avoidance strategies to minimize pain. This involuntary adaptation leads to muscle weakening and increasing restriction of movement. Activities as simple as climbing stairs, brushing hair, or getting up from a seated position gradually become problematic. It’s as if the body is gradually imprisoned within an invisible shell that restricts every movement.
