Myalgia
Myalgia refers to muscle pain that can be triggered by a variety of causes. It may occur acutely or become chronic, and most commonly affects the skeletal muscles.
Typical causes of myalgia include:
-
muscle overuse (e.g., from exercise or poor posture)
-
injuries such as strains or contusions
-
infections, e.g., viral illnesses
-
inflammatory conditions such as myositis
-
systemic diseases like fibromyalgia
-
psychological factors like stress or emotional tension
These factors can lead to muscular tension and pain of varying intensity, ranging from mild, pulling discomfort to sharp, stabbing pain. Myalgia is often accompanied by:
-
muscle stiffness
-
swelling
-
restricted mobility
Treatment depends on the underlying cause and may include:
-
rest and relief of muscle strain
-
physical therapy (e.g., heat, massage, exercise)
-
pain medication
-
relaxation techniques and stress management
In chronic cases, a multidisciplinary approach involving physicians, physical therapists, and psychotherapists may be necessary to achieve long-term relief.
