Symptoms of polymyositis

summary

Some time ago, I went back to my hometown to visit my elders. I found that people who used to be very healthy were lying in bed now. They looked much thinner. After understanding, I learned that it was caused by polymyositis. I'll tell you about the symptoms of polymyositis.

Symptoms of polymyositis

First: proximal muscle weakness or rash, general discomfort, fever, fatigue, weight loss, etc. Rhabdomus is involved, which is characterized by weakness of the proximal muscle group. It often presents symmetrical damage, with muscle swelling and tenderness in the early stage and muscle atrophy in the late stage. Most patients had no distal muscle involvement. Pelvic girdle muscle and thigh muscle weakness: unable or difficult to lift legs, unable to get on the car, go upstairs, sit down or squat down, and difficult to stand up.

Second, the flexor muscles of the neck may be seriously affected: it is difficult to raise the head when lying on the back, and the head is often tilted back. Laryngeal muscle weakness causes dysphonia, hoarseness, etc. Pharynx, upper esophageal rhabdomus involvement caused dysphagia, drinking water cough, liquid from the nostril outflow. The decrease and expansion of peristalsis in the lower esophagus and small intestine cause acid reflux, esophagitis, dysphagia, epigastric distension and malabsorption. Weakness of shoulder girdle muscle and proximal part of upper limb, upper limb can't be raised horizontally or upward, and hair can't be combed.

Third: chest muscle and diaphragm involved, appear shallow breathing, dyspnea, and cause acute respiratory insufficiency. Muscle swelling may occur in the early stage of the disease, and about 25% of the patients have pain or tenderness. Gastrointestinal tract: nausea, vomiting, abdominal pain. Gastric bleeding and even perforation. The manifestations were heart failure, pericarditis, conduction block and arrhythmia. Coronary artery changes, active vasculitis, intimal hyperplasia, occlusive arteritis, arteriosclerosis with calcification.
