Causes of Musculoskeletal Pain in MS
Musculoskeletal pain in MS has many possible causes, all of which stem from the way MS changes how your body moves, compensates, and supports itself.
Fatigue Fatigue is one of the most common MS symptoms, and it can alter movement patterns. When you’re tired, it’s harder to maintain good posture or steady gait, which increases strain on muscles and joints.
Balance Problems When balance is off, people often take shorter steps, widen their stance, or shift weight differently to feel safer. These instinctive adjustments can lead to pain in the hips, lower back, and knees, says Odonkor. “Degenerative joint disease can also be caused by abnormal weight-bearing,” he adds.
Other Mobility Challenges If you’re having difficulty standing, moving from sitting to standing, or walking long distances, this can create a cycle of inactivity and weakness. That deconditioning can cause disuse atrophy and exacerbate pain, says Odonkor.
Chronic Spasticity Chronic spasticity may lead to muscle overuse, contractures, and trigger points, says Odonkor. Stiff, tight muscles from spasticity can change the way weight is distributed across the legs and feet. Over time, the joints and soft tissues absorb extra stress, causing pain.
