Swelling and hardening of neck muscles

Swelling and hardening of the neck muscles is a clinical symptom caused by ossifying myositis disease. Myositis ossificans (musositis ossificans) is a disease of muscular sclerosis, toe and thumb deformity caused by the deposition of progressive bone structure in muscle and connective tissue. The cause is unclear. Some of them are autosomal dominant. Common in children or youth. Appears as abnormal congenital torticollis, torsion and swelling and hardening of neck muscles, but most of them without pain. All muscles can be involved. Vigorous exercise or trauma can cause muscle rupture, hemorrhage, and hematoma formation. Most patients absorb hematomas, but they can also develop muscle stiffness and ossification, eventually causing stiffness and disability of the corresponding joints of affected muscles.
