What are the common symptoms of muscle disease? What are the diseases of human muscles?

Muscle symptoms are caused by increased neuromuscular pressure. Symptoms include tingling and numbness in the limbs, spasms and stiffness in the hands and feet, which can be easily overlooked or misdiagnosed. Most cases are caused by an injury during thyroidectomy or thyroid surgery.

**Acupuncture, massage and other methods can be selected. In addition, it needs to be combined with neurotrophic drug conditioning.

Muscle diseases mainly include myositis and muscle weakness, and in patients with myositis, spasms of the limbs and muscle pain may occur. May present with toothache and muscle weakness. Cardiac enzymes, creatine kinases, and isoenzymes should be markedly elevated, and leukocytes may also be present.

For people who are recovering from the body (that is, people who are relatively weak) want to strengthen their bodies through exercise, the best way to exercise is slow, not too vigorous, the body can sweat slightly, do not sweat profusely, and it is difficult to make up for more qi injuries.

I think Tai Chi is good, the elderly can play the Yang style, the young people can practice the Chen style, which is quite good, and there is also swimming, which is also very good, and it is the most suitable for friends who want to **.

Myasthenia gravis, intramuscular ossification.

Dermatomyositis, also known as heterochromic dermatomyositis, is an autoimmune muscle inflammatory disease, and in terms of clinical manifestations, there are mainly muscle inflammation and characteristic dermatitis. Dermatomyositis is a diffuse non-infectious inflammatory disease of the muscles. **Redness, edema, muscle inflammation and degeneration cause muscle weakness, pain and swelling.

It can be accompanied by damage to various organs such as joints and myocardium. Dermatomyositis mainly involves striated muscle, which is a non-purulent inflammatory lesion dominated by lymphocyte infiltration, which can be accompanied by a variety of ** lesions, and can also be accompanied by various visceral lesions. Polymyositis refers to the disease of this group without ** damage.

Dermatomyositis is not uncommon for many people, the disease has a very high incidence in recent years, and there is no age limit, as long as you suffer from epithelial myositis, it will cause redness, edema, muscle swelling, and pain. This is very distressing for patients. Therefore, it must be timely**, and the following experts will introduce the early symptoms of dermatomyositis.

1. **The damage usually occurs on both sides of the eyelids first, and the upper and lower eyelids on both sides turn purple-red and show substantial edema, but the size of the eye fissure is normal, and the eyes are not affected when they are opened. In solar dermatitis caused by cosmetics allergies, although the upper and lower eyelids on both sides are also obviously red and swollen, the eye fissures are significantly smaller, and it is difficult to open the eyes. 2. Dermatomyositis lesions, in addition to the eyelids, often involve the entire face, including the forehead, both cheeks, cheeks, front of the ears and chin, showing diffuse redness and swelling, and there is no normal ** visible on the entire face.

At this time, gently press the red and swollen ** on the face with your fingers, which has the soft and hard feeling like pressing on a rubber block. The solar dermatitis caused by cosmetics allergies, although the face is also red and swollen, but carefully observed, the range of redness and swelling is limited to the cheeks and chin on both sides, the edge of the erythema is clear, and a lot of normal colors can be seen on the face. 3. Dermatomyositis damage, which can also involve the entire neck and the "V" area of the anterior chest**, which is diffuse redness and swelling, and there is also a soft and hard feeling of rubber blocks.

Solar dermatitis caused by cosmetics allergies has no damage in the neck and anterior chest. 4. In patients with early dermatomyositis, there are many small red rashes, guttate erythema or guttate white spots, and fine skin flakes attached to the lesions. In patients with early dermatomyositis, these subtle manifestations around the extensor sides of the large and small joints of the limbs**, muscle aches and weaknesses all over the body, and the legs feel laborious when going up stairs; When raising your hands to comb your hair, it is difficult to raise your arms high; Turning your head slowly and effortlessly is done.

There are two main types of diseases that cause muscle weakness, one of which is the disease of the muscle itself, that is, the disease of skeletal muscle. The other major category is diseases other than skeletal muscle, which are divided into two parts, one is the nerve innervation of skeletal muscle, and the other is the problem of electrolytes, that is, the electrolyte problem that makes skeletal muscle produce action potential, so that the contractile ability of skeletal muscle is weakened, and this situation will also cause muscle weakness. It is common because of the muscle weakness of skeletal muscle, mainly seen in myasthenia gravis, myositis, muscular dystrophy, etc.

If skeletal muscle weakness is caused by nerves, it may occur in motor neuron disease, brain or spinal cord disorders, or some paralysis caused by nerve damage. Electrolyte imbalances, most commonly hypokalemic paralysis, are commonly caused by muscle weakness. There are also tumors that can also cause a distant effect, causing muscle disease, called neoplastic paraneoplastic syndrome, causing myasthenic syndrome, which is also one of the causes of muscle weakness.

Myasthenia is an autoimmune disorder in which transmission is impaired at the neuro-muscle junction due to a decrease in acetylcholine receptors. The main clinical feature is that local or generalized striated muscles tend to fatigue and weakness during activity, which can be relieved by rest or anticholinesterase drugs.

Dysfunction of nerve-muscle junction transmission is an autoimmune disease of acetylcholine receptors on the postsynaptic membrane at the neuromuscular junction.

Food contamination and poisoning: A considerable proportion of patients get sick from eating unclean fried fritters, low-quality drinks contaminated with chemicals, and some are caused by patients eating mushrooms.

Viral infection: the disease is associated with immunocompromise and infection with the chronic disease virus of the thymus.

Mental factors: Excessive fatigue is caused by playing mahjong and computer games for a long time, so it is necessary to combine work and rest to maintain a comfortable mood.

other factors; Endocrine disorders, hyperthyroidism, autoimmune diseases, polymyositis, lupus erythematosus, etc.

The main symptoms of polymyositis are as follows:

1) symmetrical weakness of the limbs with tenderness;

2) Serum enzyme activity was increased, CPK and LDH were both high, especially LDH was more sensitive;

3) spontaneous fibrillation potential and normal-phase sharp wave on electromyography;

4) Muscle biopsy showed muscle fibrosis, necrosis, regeneration, inflammatory cell infiltration, vascular endothelial cell hyperplasia, etc.

Polymyositis is a group of diffuse muscle inflammatory diseases characterized by symmetrical muscle weakness of the proximal limbs, neck muscles, pharyngeal muscles, muscle tenderness, and increased serum enzymes. Most scholars believe that the disease is related to an autoimmune disorder. Some scholars believe that it is related to viral infection or genetic factors.

Most of them have a subacute onset, and can occur at any age, more common in middle-aged people and above, and slightly more in women.

Some patients have malignant tumors before the disease, and about 0% of patients have other diseases such as lupus erythematosus, scleroderma, rheumatoid arthritis, and Sjögren's syndrome. Due to the different scope of involvement, the clinical manifestations of the disease are diverse. The disease usually peaks within a few weeks to months, with generalized muscle weakness and, in severe cases, respiratory muscle weakness, which is life-threatening.

Therefore, early diagnosis and ** are very important.
