Muscle soreness is a common issue with a variety of potential causes. Intense exercise can cause microscopic tears in muscle fibres, leading to inflammation and delayed-onset muscle soreness (DOMS). Acute soreness can occur during or immediately after exercise due to lactic acid buildup, whereas DOMS usually involves muscle tightness and tenderness that begins a day or two after a workout. Dehydration, poor nutrition, and stress can also contribute to muscle soreness. In some cases, muscle soreness may be a symptom of a more serious condition, such as rhabdomyolysis, tendonitis, or an underlying illness. It is important to seek medical attention if muscle soreness persists or worsens despite rest and home care.

What You'll Learn
Dehydration and poor nutrition
During exercise, the body loses fluid through sweating and respiration, particularly in hot environments, leading to hyperthermia and dehydration. This results in an increased core body temperature, as blood flow is reduced and plasma volume decreases. As muscle temperature rises, the function of proteins involved in calcium release and uptake, as well as actin-myosin interaction, are impaired, leading to structural damage to skeletal muscles.
Dehydration can also exacerbate the symptoms of Delayed Onset Muscle Soreness (DOMS). DOMS is caused by microscopic tears and muscle damage induced by high-intensity or eccentric exercises, which involve tensing a muscle while lengthening it. Dehydrated individuals who perform eccentric exercises may experience greater skeletal muscle damage, resulting in structural, contractile, and enzymatic protein denaturation. This leads to increased muscle soreness and tenderness.
Proper nutrition is also crucial in managing muscle soreness. A well-balanced diet that includes adequate protein intake is essential for muscle recovery and repair. Protein helps repair and rebuild muscle fibers, reducing soreness and improving recovery time. Additionally, ensuring sufficient calorie intake provides the body with the energy required for muscle repair and regeneration.
To prevent and alleviate muscle soreness, it is important to stay hydrated, especially during exercise or in hot environments. Consuming water before, during, and after exercise can help reduce muscle soreness and improve recovery. Additionally, a well-balanced diet with sufficient protein and calorie intake can support muscle health and reduce soreness.

High-intensity exercise
DOMS can be uncomfortable, but it does not require medical attention. It is important to listen to your body and rest if you are experiencing soreness. While you may be tempted to rest completely, this may worsen pain and stiffness. Instead, try some gentle movement throughout the day, such as light walking, gentle yoga, or swimming. Staying active increases blood flow to the area, which can help with recovery.
There are also other ways to help ease the pain and stiffness while your muscles repair themselves. For example, a massage can help relieve tightness and increase blood flow to the area, aiding recovery. Compression garments can also help decrease muscle soreness by increasing blood flow to the area through compression. Additionally, OTC creams and gels have been found to speed up recovery from exercise-induced microtears in the muscle.
While muscle soreness after high-intensity exercise is common, soreness can also be a sign of a more serious issue. If soreness persists for more than a few days or worsens despite rest, consider seeking professional care. Additionally, a rare but serious condition called rhabdomyolysis can develop days after exercise from overexertion or heat injuries. It happens when skeletal muscle fibers break down and enter the bloodstream and usually requires emergency medical attention. Symptoms include sharp pain, muscle spasms, and numbness and tingling.

Cancerous tumours
Muscle soreness can be caused by several factors, including exercise, strain, injury, or a passing infection. In some cases, muscle soreness can also be a symptom of an underlying medical condition. One such condition is cancer, where a cancerous tumour invades or originates in the muscle tissue, leading to muscle pain.
- Direct Pressure: A tumour can press on nerves, bones, or other organs, causing pain. This pressure can lead to acute or chronic pain that persists long after the initial injury or treatment.
- Bone Damage: Cancer can spread to the bone (bone metastases) and damage bone tissue, leading to pain. This pain is often described as aching, dull, or throbbing.
- Soft Tissue Damage: Cancer can affect soft tissues, such as muscles, leading to pain. This type of pain is called visceral pain and is usually sharp, cramping, aching, or throbbing.
- Inflammation: Tumours can cause inflammation in the surrounding area, leading to muscle pain and soreness. This may be due to the release of certain chemicals and growth factors that alter muscle function and cause discomfort.
- Nerve Compression: In advanced cancer, tumour growth can lead to nerve compression, resulting in pain and other neurological symptoms.
It is important to note that muscle soreness caused by cancerous tumours may be accompanied by other symptoms, such as fatigue, reduced tolerance to treatments, impaired quality of life, and reduced survival rates. Additionally, cancer treatments themselves can also cause muscle pain, such as through chemotherapy or radiotherapy.
If you are experiencing persistent or unusual muscle soreness, it is always best to consult with a healthcare professional. They can help determine the underlying cause and provide appropriate treatment or referrals.

Infections and illnesses
Muscle soreness can be caused by a variety of infections and illnesses. Localized muscle pain or soreness in one spot is often related to a specific event, like an injury or recent stress on that muscle group. For example, strains, sprains, and other injuries can cause muscle pain and discomfort, and a particular area of the body can become stiff and achy if it is injured. Additionally, muscle soreness can be a symptom of a passing infection, which usually improves with rest and home care. However, if soreness persists or worsens despite rest, it could indicate a more serious infection or condition requiring professional care.
In some cases, muscle soreness may be a sign of an underlying condition or illness. When aches occur throughout the entire body, it often suggests a systemic issue such as an infection, medication side effect, or underlying illness. For instance, dehydration and electrolyte imbalances can lead to muscle stiffness and soreness, and proper hydration is recommended to alleviate this issue. Similarly, nutritional deficiencies, especially a lack of vitamin D and calcium, can contribute to muscle aches and soreness. Ensuring adequate nutrient intake through a balanced diet or supplements may help address this cause.
Certain medical conditions can also lead to muscle soreness. For example, tendonitis, an inflammation of a tendon, is a common overuse injury that can cause muscle pain. Additionally, muscle stiffness or soreness may be a symptom of more serious conditions such as multiple sclerosis (MS), cerebral palsy, or amyotrophic lateral sclerosis (ALS). In some cases, muscle soreness can be a sign of cancer, although this is relatively rare. A cancerous tumor originating in or invading muscle tissue can cause muscle pain, and these cancers are known as sarcomas.
Furthermore, stress can be a contributing factor to muscle soreness and aches. When individuals are stressed, their bodies may find it more challenging to fight off disease and inflammation, leading to muscle pain. Learning relaxation techniques and removing oneself from stressful situations can help manage stress-related muscle soreness. Overall, while muscle soreness is often associated with exercise or physical activity, it is important to consider the potential role of infections and illnesses as underlying causes, especially when the soreness is persistent or widespread.

Stress and tension
Stress-related muscle pain can be a sign of a flare-up of symptoms of other conditions, such as arthritis and fibromyalgia, as stress lowers the body's threshold for pain. It is important to note that stress may not be the direct cause of these conditions, but it can exacerbate their symptoms, creating a cycle where increased physical symptoms lead to heightened stress.
Chronic stress can lead to a range of physical symptoms, including muscle aches and pains, sleep problems, and gastrointestinal issues. Stress can also cause hormonal changes, resulting in decreased sex drive, erectile dysfunction, irregular menstrual cycles, and missed periods.
To alleviate stress-related muscle soreness, it is beneficial to find healthy ways to manage stress. Engaging in creative activities, such as painting, writing, or playing music, can effectively reduce stress levels. Developing healthier coping mechanisms, such as exercising, calling a friend, or going for a walk, can provide deeper and more long-lasting stress relief.
Additionally, self-care practices can help soothe sore muscles. Resting gives strained muscles a chance to heal and recover, while gentle stretching can prevent stiffness. Massage is another effective way to relieve tension and improve blood flow to sore muscles, aiding in the healing process.
