Myalgia, simply said, is a muscle pan. In myalgia the pain mainly originates in the muscles and may be related to any muscle of the body. While soreness of muscles is a common complaint, some people may experience myalgia for a considerably longer time. It is important to evaluate the causes of myalgia and plan proper treatment to manage myalgia effectively. It is advisable to seek medical opinion for diagnosis and treatment of myalgia. Home remedies for myalgia are also a great option for some cases.

Muscles are present in every part of the body. Skeletal muscles, which are the muscles that support the bones and surrounding parts are the most commonly affected muscles in myalgia. Muscle pain or myalgia may be present in a single muscle or in a group of muscles that covers a larger area. Many people experiencing myalgia often complain of varying degrees of pain, from mild to severe and the symptoms of myalgia may also change their presentation in many people. As myalgia is a widely occurring condition, it is important to understand the various possible causes of myalgia and the possible underlying medical conditions.

Causes of Myalgia

Causes of Myalgia

Myalgia is general or specific pain in muscles and as there are several muscles in the body, there are numerous causes of myalgia that lead to muscular pain.
Some of the causes of myalgia are considered here.

Overuse of Muscles Cause Myalgia

Many people are involved in activities, occupations or sports that require repeated use of a specific group of muscles. People who use the computer are often seen to experience pain in the neck, back and hand muscles. Similarly, the case with people lifting heavy objects, playing or involving in activities that need repeated use of hands, legs or need to make forceful movements. This does not give enough rest to the muscles and they work more than their capacity to get strained, which results in pain. Overuse of muscles or repetitive strain injury is a common cause of myalgia.

A Major Cause of Myalgia is Injuries

Injuries are one of the most common cause of myalgia. Injuries to the neck or back, hands or limbs or any body part can result in strained muscles around that part. Injury to bones or fractures, injured soft tissues, ligament or cartilage tears or intervertebral disc issues in the spine like disc herniation, etc. often damage the surrounding muscles and can be one of the major causes of myalgia. Injuries are commonly noted in sportspersons, falls, blows, accidents or when people try to lift heavy objects or overstrain their muscles.

While injuries can cause myalgia or muscle pain during the acute phase, many injuries also affect the soft tissues and cause long term myalgia in many cases. Injuries often make the injured area weak and more susceptible to further injuries or more sensitive to slight overuse, which can cause myalgia, in the injured muscles.

Infections and Myalgia

Infections, particularly viral fevers, influenza or those infections, which affect the muscles are also known to cause myalgia. Some infections, which can cause myalgia include malaria, dengue, Ebola and other fevers that cause damage to the muscles. Infections like polio not only cause myalgia but also affect the strength and capacity of the muscles. Most fevers have myalgia or dull aching muscle pain in the body as an associated symptom. Bacterial infections like tuberculosis, when affect the spine and muscles can cause myalgia too. Serious infections like HIV/AIDS can cause pain in muscles and myalgia.

Sensitive Points in Muscles can Cause Myalgia

Many people experience myalgia as a result of increased stress or tension building up in the muscles. Certain areas in muscles may remain sensitive to either a previous injury, infection or strain, which can repeatedly get triggered and cause myalgia. These points are similar to trigger points, which, with the slightest trigger like a jerk, a straining activity, fever, overuse, etc. can initiate pain in the muscles.

Joint and Muscle Conditions Can Cause Myalgia

Many conditions involving the joint and muscles in the body often cause myalgia. In fact muscular pain is almost always present in any condition affecting the bone, joint and muscles. Conditions like rheumatoid arthritis, osteoarthritis, septic arthritis or any form of arthritis can cause myalgia and the severity often varies with the main underlying condition.

Autoimmune Disorders and Myalgia

Certain autoimmune disorders may cause muscular pain and myalgia. Some of the common conditions like polymyalgia rheumatic, connective tissue disorders, lupus (SLE) or multiple sclerosis can affect the muscles and cause myalgia.

Medical Conditions Causing Myalgia

Some medical conditions like thyroid disorders, fibromyalgia, low muscle tone, reduced levels of potassium in blood, peripheral neuropathy, lifestyle disorders that cause fatigue or pain in the muscles can cause myalgia. Other conditions of the endocrine system or some genetic conditions too can cause myalgia. These may also be associated with other symptoms of the muscles apart from myalgia, in most cases. Chronic fatigue syndrome is also a common condition that can often cause myalgia.

Myalgia Caused Due to Medications

Certain medications or their withdrawal can cause myalgia too. Medicines like cholesterol lowering drugs, blood pressure control drugs or other treatment modalities that affect the muscles can cause myalgia. Stopping of some medicines like steroids, caffeine, opioids, medicines or sudden stopping of alcohol can result in withdrawal symptoms and cause myalgia.

Others Causes of Myalgia

Sometimes, dehydration, excessive loss of fluids due to vomiting, diarrhea, etc. too can cause myalgia. Other causes of myalgia may also include certain types of cancers, treatment of cancer or post-surgical period, in some cases. Myalgia may also be triggered in some people experiencing chronic stress, anxiety or lack of adequate sleep. Post-traumatic stress disorder, mood problems, hormonal imbalances, or other stressors too can contribute to muscle pain or worsen myalgia in some cases.

Symptoms of Myalgia

Myalgia is mainly pain in the muscles. The other symptoms of myalgia include a feeling of soreness in the muscles, a strained feeling that may make movements painful and difficult. Myalgia may also present with signs of acute injury like swelling, redness or bruising in or around the injured area.

Muscle weakness is another commonly associated symptom of myalgia. The muscle strength may not be adequate and the person may not be able to perform using the painful group of muscles. For example, if the neck or hands are affected, myalgia is often associated with weakness of muscles in arms and hands. This can make it difficult or painful for a person to lift of hold objects, raise objects overhead or may cause discomfort on performing related activities.

Myalgia may be accompanied by stiffness in the muscles and the joint nearby making movements painful. Muscles often get tensed and muscles spasms is another symptom of myalgia. Some may even experience muscle twitching or contractions of the muscle around the painful or weak muscle area. If a nerve gets pinched due to the tense muscles, it can cause pain along the course of nerve along with myalgia. In such cases, there may be numbness, tingling or burning sensation and pain in the limbs, depending on which muscle group is affected.

Daily activities may get affected due to myalgia and other complaints. Symptoms of myalgia can make it difficult for a person to perform tasks and long standing complaints can give rise to feeling of despair. Some people complain of worsening of symptoms of myalgia on overexertion, travelling, playing or performing strenuous activities. Some may even notice a change in their symptoms or worsening in myalgia with changes in the weather, during certain phases or during fevers.

Diagnosis of Myalgia

Myalgia, has a complex set of symptoms and needs proper evaluation not only to diagnose myalgia but also to detect the underlying condition that is the cause of myalgia.

Clinical examination may be helpful to determine muscle strength, muscle functioning and the overall performance. History helps to find out previous injuries, medical history and consumption of certain medicines, etc.

Some of the investigations done to diagnose myalgia and find the causes of myalgia include,

Blood tests may be advised to detect the presence of infection, in case of fevers, inflammation or when certain infections, autoimmune disorders or arthritis like conditions are suspected.

Scans may include X-rays, to study bony abnormalities, fractures etc. of concerned area, if found appropriate, as in cases if injuries, arthritis, degenerative conditions, etc. CT scans or MRI may be ordered to detect any abnormality of the bone, muscles and soft tissues in the suspected area to help to diagnosis of myalgia. It can also help to detect the presence of growths, compression or muscle injuries, which can help to confirm the cause of myalgia.

Electromyography and nerve conduction studies may be considered to determine the conduction of signals through the muscles and involvement of nerves that supply the muscles.

Treatment of Myalgia

The main aim of treatment of myalgia is to relieve pain, reduce swelling and discomfort in the area, improve movement and also treat the underlying cause.

Medications like anti-inflammatory drugs, muscle relaxants, to relax the muscles and reduce pain are usually given. Other medicines that help to relieve anxiety, reduce cramps and numbness in hands may be considered. If found appropriate or if muscle cramps are present, calcium and vitamin supplements may be considered. Dehydration and electrolyte imbalance may be treated with appropriate supplements and increased water intake.

Physical therapy may be advised, which can help to relieve pain, to treat myalgia and improvement movements. Initially, rest may be advised and necessary physical therapy treatment may be applied. This is usually followed by gentle stretching exercises and gradually muscle strengthening exercises. Progressive exercises must be followed to help improve the muscle strength and prevent myalgia.
