Myalgia (Muscle Pain): What It Is, Causes & Relief

Muscle pain is something almost everyone experiences at some point. Whether it’s the soreness after a tough workout or an ache that comes out of nowhere, muscle pain can disrupt daily life. This condition is medically referred to as myalgia. While usually temporary, in some cases, myalgia can be a symptom of a more serious condition.
Understanding what myalgia is, what causes it, and how to find relief can make a big difference in managing your health and preventing discomfort from turning into something long-term.
What is Myalgia (Muscle Pain)?
Myalgia is the medical term for muscle pain. It can range from mild discomfort to intense pain that affects mobility. Unlike joint pain or bone pain, myalgia specifically originates in the soft tissues of the body—muscles, tendons, and ligaments.
It may affect just one muscle group or the entire body. For example, you might feel localized pain in your back from sitting too long, or you might feel widespread muscle aches during a flu infection.
Why Understanding Muscle Pain Matters
At first glance, muscle pain might seem harmless. But ignoring recurring or severe myalgia could mean missing early warning signs of chronic illnesses, infections, or even medication side effects. Recognizing patterns in muscle pain helps with early intervention internal medicine, and proper treatment.
Common Causes of Myalgia
Overuse and Strain
Have you ever hit the gym after weeks of inactivity and felt sore the next day? That’s overuse myalgia. When muscles are pushed beyond their normal limits, tiny tears occur, causing soreness. Overuse is one of the most common causes of myalgia and usually resolves within days.
Injuries and Trauma
Acute muscle discomfort can result from muscle fiber loss caused by sports injuries, falls, accidents or critical cares. Additionally, injuries may result in bruising, swelling, or even muscle spasms that exacerbate the pain.
Poor Posture and Ergonomics
Spending hours hunched over a laptop or standing incorrectly can strain muscles over time. Poor ergonomics not only cause pain in the back and neck but can also lead to chronic myalgia if not corrected.
Infections That Trigger Muscle Pain
Certain infections—like influenza, Lyme disease, or even COVID-19—can cause body-wide muscle aches. These aches often accompany fever, fatigue, or general weakness, making the body feel heavy and sore.
Chronic Conditions
Conditions such as fibromyalgia, arthritis, and chronic fatigue syndrome are often linked with long-term myalgia. Unlike temporary soreness, chronic myalgia tends to persist for months and significantly affects daily functioning.
Medication-Induced Myalgia
Some medications, particularly cholesterol-lowering drugs (statins), are known to cause muscle pain as a side effect. If muscle aches start after beginning a new medication, it’s worth discussing with a doctor.
Symptoms and Signs of Myalgia
Localized vs. Widespread Pain
Myalgia can be localized, affecting only one muscle or group, or widespread, impacting multiple areas of the body. Localized pain is often linked to overuse or injury, while widespread pain may indicate an underlying health issue.
Stiffness and Limited Mobility
Muscle pain often brings stiffness, making it harder to move freely. Stiff muscles can restrict daily activities, from bending to walking, and may worsen if untreated.
Associated Symptoms
Muscle pain sometimes comes with other symptoms such as:
Fatigue
Fever
Muscle weakness
Swelling or redness
These associated symptoms help in identifying whether the myalgia is minor or part of a larger health problem.
Risk Factors for Myalgia
Lifestyle Choices
Lack of physical activity, dehydration, poor diet, or overexertion all increase the risk of muscle pain. Stress also plays a surprising role, as tense muscles are more likely to hurt.
Age and Gender
As we age, muscles naturally lose strength and flexibility, making them prone to pain. Women, due to hormonal changes, may also experience muscle pain more frequently than men.
Occupational Risks
Jobs that involve repetitive movements, heavy lifting, or long hours of sitting can put individuals at higher risk for chronic muscle pain.

FAQs - About Myalgia (Muscle Pain)
Myalgia, or muscle pain, can be caused by a wide range of factors. The most common causes include muscle overuse, injuries, and poor posture. Infections such as influenza or COVID-19 may also trigger widespread muscle aches. Chronic health conditions like fibromyalgia, arthritis, or autoimmune disorders can lead to persistent myalgia. Additionally, some medications, particularly statins (used to lower cholesterol), list muscle pain as a side effect.
Myalgia can be broadly classified into three main types:
Localized Myalgia – Pain limited to one muscle or a specific muscle group, often caused by injury or strain.
Widespread Myalgia – Muscle pain affecting multiple areas of the body, usually linked to chronic illnesses like fibromyalgia.
Systemic Myalgia – Muscle pain that occurs as part of a broader medical condition, such as infections, autoimmune diseases, or side effects of medications.
Malaise refers to a general feeling of discomfort, fatigue, or uneasiness, often accompanied by myalgia (muscle pain). Both are common symptoms of infections like flu, COVID-19, and other viral illnesses. When malaise and myalgia occur together, they usually signal the body’s immune system is fighting off an infection.
