What causes muscle inflammation

definition

Under a muscle inflammation, also "Myositis“Called, one understands an inflammatory process that takes place in the muscle. Such myositis can have a wide range of causes. It is not always bacterial or viral pathogens that trigger the inflammation, but also degenerative diseases or Autoimmune reactions can be behind it.

It will be between three forms of muscle inflammation: the so-called "Polymyositis", the "Dermatomyositis" and the "Inclusion body myositis“, Whereby the polymyositis and dermatomyositis are very similar. The most commonly affected group Adults over 50 but children are also sometimes affected.

Depending on the cause, the muscle inflammation must be treated differently. Inflammation caused by pathogens can often be eliminated well, systemic or degenerative causes often require lengthy treatment. Accordingly, the forecasts are also very different.

The clinical picture of affected patients can range from a symptom-free course to Muscle paralysis contain a lot.

causes

The causes of muscle inflammation are numerous. Muscle inflammation is one rather rare disease and when it occurs, it affects it mainly children or the elderly People. Identifying the type of myositis that is present often helps identify the cause.

Muscle inflammation is only very rarely caused by pathogens. These include above all bacteria, Viruses or Parasites. In our regions they are of no clinical relevance. Myositis is often an accompanying symptom of systemic inflammatory reactions in the body. Above all, this includes rheumatic inflammation.

Are not uncommon Autoimmune reactions the cause of muscle inflammation. Detects this in autoimmune reactions immune system mistakenly the body's own structures as foreign and tries to eliminate them. In myositis, the reaction is directed against small blood vessels in the muscle. As a result, the blood circulation deteriorates and the muscle may atrophy.

The polymyositis takes place in most of the cases no clear cause. This is called "idiopathic“.

Especially with dermatomyositis there is a risk of a Tumor disease the cause is. If dermatomyositis is newly diagnosed, a tumor must therefore always be considered, above all Ovarian cancer are common in this context.

Symptoms

Common symptoms of muscle inflammation are Muscle weakness, but also local pain and muscle pain. A inflammation is defined, among other things, by 5 main symptoms. These include pain, overheating, redness, swelling and functional impairment. These symptoms can also often be observed with muscle inflammation.

The location of the pain depends on the location of the inflammation. Any muscle can potentially be affected, from the neck to the leg. Many patients also give the feeling of one Sore muscles at. It can also difficulties swallowingcome.

Since some of the vessels also have musculature, the blood vessels may also be involved, a "Vasculitis". A symptom of this is the "Raynaud's Syndrome“, In which there is lightening and darkening of the skin color, especially on the fingers, caused by cramping of the blood vessels supplying it.

The extension of the polymyositis is the dermatomyositis. With it, the inflammation spreads into the skin and in addition to the symptoms of muscle inflammation, there is reddening and swelling of individual skin areas.

diagnosis

For the diagnosis of muscle inflammation, the most important ones are clinical symptoms crucial. Typical first signs are Muscle weakness and local Pain at the site of inflammation. However, symptoms develop very slowly in most cases. There are other examination methods in the clinic that allow a more precise diagnosis.

Especially Blood tests allow conclusions to be drawn about muscle inflammation. Inflammation parameters in the blood indicate acute inflammation. The most important here are CRP, Leukocytes and sedimentation rate. If they are increased or changed, this indicates an inflammation in the body. Other values ​​point to the muscle as the origin, including so-called "LDH, transaminases, creatine kinase and myoglobin". These molecules are mainly found in muscles and indicate that muscle cells have been destroyed if they are found in increased numbers in the blood.

For a reliable diagnosis if a muscle inflammation is suspected, this counts biopsy. A small needle is inserted into the affected muscle in order to remove tissue and examine it closely. If a tissue sample is reached from the right place, which is not always possible, the exact diagnosis can often be made and the type of myositis determined.

therapy

If you experience persistent muscle weakness and severe pain, you should consult a doctor. Since muscle inflammation is a rather rare disease in our regions, it is not always easy to make a clear diagnosis.

However, if there is a suspicion of inflammation and if it is, for example by a Tissue sample confirmed, must therapy started immediately to stop the inflammatory process. Otherwise, chronic, painful inflammation can occur, which in the long term leads to a strong reduction in muscle mass.

A immediate protection is important for the affected muscle region. The doctor becomes medication cortisone- Prescribe preparations. These take effect after a few days to weeks, in some patients it can take up to 6 weeks for improvement. The therapy is controlled with constant blood testsuntil the inflammation levels and muscle-specific enzymes in the blood return to normal.

In severe cases which even cortisone preparations cannot help with Immunosuppressants be taken. They lower the immune system and thus also reduce the body's own inflammatory reaction. However, this makes the body more sensitive to all kinds of pathogens.

With certain muscle groups, there is also one during the acute phase of the inflammation physiotherapy at. Especially when the Swallowing or breathing muscles this is important so that these do not lose too much of their function.

General rehabilitation is only possible when the inflammation has healed or is no longer in an acute phase. Gentle too long goes with one loss of still existing Muscle functions a. The goal of rehab is to maintain as many functions as possible and, after the inflammation has subsided, to rebuild muscle functions as well as possible.

Inflammation of the muscles in the arm

There is an inflammation of the muscles in the area of ​​the arm and especially the entire upper arm not infrequently. It is often triggered by rheumatic inflammation. One symptom of arm myositis is this Muscle weakness. Especially with muscles close to the torso, weakness and slackening quickly develop.

The affected patients often notice the inflammation of the muscles in the arm when they enter Sore muscles feeling without cause to have. The sore muscles cannot then be traced back to previous sporting activity. It quickly leads to the patient being unable to raise their arms above a certain level.

After a precise diagnosis has been made, therapy must be initiated immediately before degenerative changes in the muscle occur. Above all, rest and drug therapies must first be observed. After healing, a physical therapy become necessary.

Inflammation of the muscles in the calf

The calf muscles can also be affected by muscle inflammation. Muscle parts that are close to the torso are quickly affected. Thighs and calves are therefore often affected.

With initial myositis, one develops over a long period of time Muscle weaknessmade by a local pain can be accompanied. The feeling of sore muscles can also occur without the Leg muscles was actively used. If there is also swelling and redness in the calf, inflammation is likely.

The main problem for the patient is muscle weakness in everyday life. Simple everyday tasks such as climbing stairs become a pain in the case of severe muscle inflammation. Often the inflammation spreads symmetrically from the torso. Only the legs are rarely affected.

A rare phenomenon in muscle inflammation can be observed in the area of ​​the calf. Protracted inflammatory processes lead to a "Pseudohypertrophy“The calf muscles. The calf thickens as if a lot of muscle mass had built up in a short time. However, the body effectively breaks down and replaces muscle with connective tissue and Adipose tissue. The calf becomes larger, but the muscle strength is reduced.

Inflammation of the muscles of the shoulder

Especially those shoulder is a frequently affected muscle area in inflammatory changes. It is directly adjacent to the trunk muscles from which many inflammations originate.

In most cases, both shoulders are affected symmetrically. The Shoulder muscles not only plays a role in shoulder-to-trunk movements, but also in rotating and lifting the arm. Affected patients often complain Muscle weakness With pain trying to raise your arms. Long-term inflammations can also affect the shoulder muscles Loss of muscle masse come, which is mainly replaced by adipose tissue.

Together with the Arm muscles often needs the shoulder area after an inflammation physiotherapy for the regeneration of muscle strength.

Inflammation of the muscles in the chest

If there is inflammation of the muscles in the chest, it can often be small hardened nodules Keys. These are foci of inflammation. The inflammation in the Chest muscles mostly occurs symmetrically and can be acute or chronic. Especially when she's through Pathogen is caused, it often has an acute, painful but completely resolving course. Many bacterial or viral pathogens are possible. Inflammation from parasites is extremely rare.

The inflammation arises in the chest mostly without a cause, so idiopathic.

In the case of long chronic courses, so-called "atrophies" of the muscle also occur here, i.e. a reduction in muscle mass. The chest muscles are attached to the upper arm and are mainly responsible for the rotation of the arm. This occurs when there is inflammation Feelings of weakness, more burning aching or, in the case of acute inflammation, especially stabbing Pain on.

Inflammation of the muscles in the neck muscles

In many cases, muscle inflammation spreads from the trunk to the Neck muscles out. The myositis in the neck is particularly uncomfortable in everyday life. The neck muscles allow every movement of the head, both rotations and easy holding up.

Strength muscle pain and Feelings of weakness lead to the fact that the patient can move the head very restricted. Everyday things, such as driving a car, become almost impossible.

Also localized in the throat Throat and pharynx muscles. With severe muscle inflammation, these muscle groups are restricted. difficulties swallowing are a common consequence. Every movement is painful and agonizing for the patient. Immediate protection, if this is possible in the throat area, and medical treatment by the doctor will be necessary.

In serious cases, the inflammation can extend to the Respiratory muscles spread, which can sometimes be life-threatening. High dose Cortisone therapies must then be set by the supervising doctor.

Inflammation of the muscles in the elbow

One form of muscle inflammation is the so-called "Myositis ossificans“In the course of accidents, injuries occur, as a result of which tissue becomes ossified in the wrong places. On the one hand, this can be hereditary and progressive Ossification of connective tissue, or as a result of injuries or operations.

Especially in the Elbow joint ossifying muscle inflammation is a rare side effect of injuries, including operations.

The ossification can possibly spread to the upper arm muscles. Immediate therapy, including surgery, must be started immediately to stop the process. Permanent damage and impairment of joint function is a possible consequence. The joint then becomes more and more rigid and immobile due to the increasing bony structures.

Myositis is often noticeable when severe pain still occurs after a few days to weeks after an injury and treatment. In radiological images, the ossification can unfortunately only be determined after it has long been active.

Inflammation of the muscles in the shin

Similar to the calf muscles, myositis can also develop in the muscles around the Shin unfold around. Restrictions in movement, muscle weakness and pain are the result. Direct pain in the shin is rather rare. The pain only becomes noticeable when there is local pressure on the affected area or when the Lower leg muscles. Resting is then indicated.

therapy

If you experience persistent muscle weakness and severe pain, you should consult a doctor. Since muscle inflammation is a rather rare disease in our regions, it is not always easy to make a clear diagnosis.

However, if there is a suspicion of inflammation and if it is, for example by a Tissue sample confirmed, must therapy started immediately to stop the inflammatory process. Otherwise, chronic, painful inflammation can occur, which in the long term leads to a strong reduction in muscle mass.
