Muscle induration

Introduction Muscle induration is a chronic, repeated accumulation of microscopic damage. It often occurs in areas with excessive muscle activity or persistent muscle tension in static posture. Can be divided into two categories of acute and chronic. Common parts are the muscles of the waist, neck and legs. The essence is a kind of aseptic inflammation, which is caused by the muscles that control the hyperactive or weight-bearing joints or the ligaments that support these joints, especially the attachment points of muscles or ligaments on the bone. Repeating a particular action for a long time and often is a common cause of overloading.

Cause

The essence is a sterile inflammation, mainly manifested by pain, tenderness and dysfunction in the affected area. Strain damage occurs in the muscles that govern the hyperactive or weight-bearing joints or the ligaments that support these joints, especially the attachment of muscles or ligaments to the bone. Repeating a particular action for a long time and often is a common cause of overloading.

Muscle weakness, fatigue, soreness, local tenderness, limited range of activity, decreased labor capacity, followed by persistent pain, soreness, muscle induration, dysfunction, etc.

Combined with medical history and clinical manifestations, relevant examinations are carried out to summarize and analyze, and several possible diagnoses are proposed, and then further examinations are performed to confirm the diagnosis.

Differential diagnosis

Muscle induration symptoms are often accompanied by muscle weakness, pain, soreness, local tenderness, limited range of motion, and need to be differentiated from the following symptoms: muscle tear: muscle strain is a muscle contraction or excessive traction during exercise Damage caused. This is easy to occur during long, pull-ups and sit-up exercises. After the muscle strain, the painful part of the strained area can be touched by the muscles of the muscles, and the pain is obvious. The local swelling or subcutaneous hemorrhage is obviously restricted.

Muscle contracture: the fascial fibrosis of the fascia where muscles and muscles are located, contractures, and clinical symptoms of specific gait and signs manifested by limited joint function.

Muscle contusion: A non-open injury that occurs when a blunt object acts directly on the soft tissue of the carcass.

Muscle strain: An injury caused by a sharp contraction or excessive pulling of muscle during exercise. Muscle strain is a damage caused by a sharp contraction or excessive pulling of muscles during exercise. This is easy to occur during long, pull-ups and sit-up exercises. After the muscle strain, the painful part of the strained area can be touched by the muscles of the muscles, and the pain is obvious. The local swelling or subcutaneous hemorrhage is obviously restricted.

Muscle tenderness: Muscle tenderness is a clinical manifestation of polymyositis. Polymyositis is a group of patients with unclear etiology. The main clinical manifestations are diffuse muscle inflammatory diseases characterized by symmetric proximal extremities, cervical muscles, pharyngeal muscle weakness, muscle tenderness, and increased serum enzymes. Muscle bruises: Muscles: mainly composed of muscle tissue. The shape of muscle cells is slender and fibrous, so muscle cells are often called muscle fibers. Muscle bruises are crushed by objects to damage muscles.

Muscle bruises: Muscles are hit by foreign objects, causing pain, congestion, redness, dysfunction, muscle spasms, deformities and other symptoms.
