Muscle soreness, known as delayed onset muscle soreness (DOMS), is a common consequence of working out. It occurs when muscles and the connective tissue around them get damaged during exercise, causing microscopic tears in the muscle fibers. This damage triggers an inflammatory response, leading to the soreness felt after a strenuous workout. DOMS typically sets in 24 to 72 hours after novel or eccentric-heavy exercises and can last for a few days. While it is a normal part of the muscle-building process, experiencing excessive soreness or prolonged pain may indicate an injury or condition requiring medical attention.

Muscle pain from exercise
Muscle soreness after exercise is a common phenomenon, often referred to as Delayed Onset Muscle Soreness (DOMS). It is characterised by a sore, aching, painful feeling in the muscles after engaging in a new or strenuous physical activity. DOMS usually sets in a day or two after a workout, peaking at 24-72 hours, and should resolve within a couple of weeks.
DOMS is caused by temporary muscle damage and inflammation, specifically by microscopic tears in the muscle fibres, which develop during exercise. Eccentric exercises, which involve putting a load on a muscle while lengthening it, are particularly associated with DOMS. This type of exercise includes movements such as stretching out your arm after a bicep curl.
The good news is that muscle soreness after exercise is a normal part of the body's adaptation process. When muscles are exposed to new or strenuous activity, they undergo minor damage at the microscopic level, prompting the body to repair and strengthen them, making them more resilient for the future. This process is vital for improving muscular strength and performance.
While muscle soreness after exercise is typically harmless, there are some instances where it may require medical attention. If the soreness is accompanied by symptoms such as dark urine, muscle cramps, or fatigue, it could indicate a rare but serious condition called rhabdomyolysis (rhabdo), which requires immediate medical care. Additionally, sharp pains that occur immediately after exercise could signal injuries such as strains or sprains, which may also need medical attention.
To alleviate muscle soreness after exercise, several strategies can be employed:
- Light exercise: Engaging in gentle activities like walking, swimming, or yoga can increase blood flow to the sore muscles, promoting healing and reducing soreness.
- Massage: Massage therapy can help alleviate muscle soreness by increasing blood flow to the affected area and reducing inflammation.
- Hot or cold therapy: Applying heat can increase blood flow and reduce stiffness, while cold therapy can help reduce inflammation.
- Stretching: While there is conflicting evidence about its effectiveness, stretching before or after exercise may help alleviate muscle soreness for some individuals.
- Anti-inflammatory aids: Consuming foods with natural anti-inflammatory properties, such as watermelon, cherry juice, or pineapple, may help reduce soreness. Additionally, magnesium supplementation has been shown to reduce muscle soreness and improve recovery.
- Protein intake: Consuming protein, which is made up of amino acids, provides the building blocks for muscle repair and rebuilding.
- OTC creams and gels: Topical applications have been found to speed up recovery from exercise-induced microtears.

Underlying medical conditions
Muscle pain, or myalgia, is extremely common, and almost everyone experiences it at some point. While it is often temporary and not serious, chronic muscle pain can be a symptom of an underlying medical condition.
Muscle pain from temporary causes, such as exercise, strain, or a passing infection, usually improves with rest and home care. However, if the pain persists or worsens despite rest, it could indicate a more serious issue requiring professional care. For instance, muscle stiffness can sometimes point to an underlying, more serious infection or medical condition.
Muscle pain can be caused by various underlying medical conditions, including:
- Autoimmune diseases, such as multiple sclerosis, lupus, inclusion body myositis, and polymyositis
- Infectious diseases, such as colds, influenza, malaria, trichinosis, Lyme disease, and Rocky Mountain spotted fever
- Medications and therapies, such as statins, angiotensin-converting enzyme (ACE) inhibitors, chemotherapy, and radiotherapy, which can cause short-term and long-term muscle pain
- Neuromuscular disorders, such as spinal muscular atrophy (SMA), myasthenia gravis (MG), Duchenne muscular dystrophy (DMD), and amyotrophic lateral sclerosis (ALS)
- Other health conditions, such as stress, electrolyte imbalance, peripheral artery disease, hypothyroidism, fibromyalgia, compartment syndrome, chronic fatigue syndrome, sarcomas, and leukemia
If the cause of muscle pain is unknown or it is severe or chronic, doctors may recommend additional tests, such as blood tests, to determine enzyme, hormone, and electrolyte levels and check for signs of infection.

Dehydration
Drinking water is crucial before, during, and after physical exercise to maintain proper hydration levels. However, it is important to note that water intake alone may not be sufficient to prevent muscle cramps. Electrolyte-rich fluids or foods can help maintain electrolyte balance and reduce the risk of muscle cramping. Consuming oral rehydration solutions (ORS) or sports drinks that contain electrolytes can be beneficial. Additionally, eating a balanced diet that includes foods rich in potassium, magnesium, and sodium, such as bananas, can support electrolyte balance.
The connection between dehydration and muscle cramping is particularly relevant after strenuous exercise or exposure to heat, as the body loses significant amounts of water and electrolytes through sweating. Therefore, it is essential to prioritize rehydration and electrolyte replacement during and after such activities.
While dehydration is a contributing factor to muscle cramping, it is not the sole cause. Other factors, such as inadequate diet, certain medications, and overuse of muscles, can also increase the likelihood of muscle cramps. Maintaining proper nutrition, staying well-hydrated, and allowing muscles to rest and recover are crucial in preventing dehydration-related muscle cramps.
If muscle cramping persists or causes frequent discomfort, it is important to consult a healthcare professional for guidance and treatment. They can provide advice on proper hydration, nutrition, and muscle care to help alleviate cramping and improve overall muscle health.

Stress
One of the most common physical symptoms of stress is muscle tension, which can lead to pain, stiffness, and soreness in various parts of the body, including the back, neck, and shoulders. This is because when the body is under stress, it releases a hormone called cortisol, which can increase inflammation and cause pain. Stress can also lead to poor posture and inactivity, further contributing to muscle pain. Tension headaches are a common manifestation of this, caused by the tightening of muscles in the head, face, and neck.
Additionally, stress can lower your threshold for pain, leading to flare-ups of symptoms of arthritis, fibromyalgia, and other conditions. It can also cause gastrointestinal symptoms such as abdominal pain, heartburn, nausea, diarrhoea, and constipation.
To alleviate stress-related muscle pain, regular exercise, stress management techniques, good sleep hygiene, and a balanced diet are recommended. Mind-body practices such as yoga and tai chi, as well as mindfulness meditation, have been shown to be effective in reducing stress and its associated muscle tension. Connecting with family and friends, spending time in nature, and engaging in creative activities can also help to reduce stress levels.
If stress-related muscle pain is persistent or chronic, it is important to consult with a healthcare professional for guidance and support.

Infections
Myositis is a condition that causes inflammation in the muscles, resulting in weakness, swelling, and pain. It can be caused by infection, injury, autoimmune conditions, or drug side effects. While the exact cause of myositis is unknown, viral infections are the most common infectious cause, with bacteria, fungi, or other organisms being rarer triggers. Viruses or bacteria can directly attack muscle tissue or release substances that damage muscle fibres. Examples of viruses that can cause myositis include common cold and flu viruses, as well as HIV. Pyomyositis, a rare bacterial infection, can cause an abscess in the muscles, most commonly in the thigh muscles. It is caused by the bacteria Staphylococcus aureus (a staph infection) and is treated with antibiotics.
Infectious myositis can be caused by a broad range of bacterial, fungal, parasitic, and viral agents. Bacterial and fungal myositis typically affects a specific muscle group and occurs in immunosuppressed patients in temperate regions. Viral myositis, on the other hand, is often diffuse and can be caused by various viruses such as cytomegalovirus, Epstein-Barr virus, herpes simplex virus, and varicella-zoster virus. The diagnosis of infectious myositis is suggested by serologic studies or culture results from nasopharyngeal or stool specimens. Muscle biopsies are rarely performed to identify the virus, and most biopsies do not reveal a direct viral effect, suggesting an immune-mediated pathogenesis.
Musculoskeletal infections are caused by the invasion of disease-causing organisms into an individual's muscles, bones, or joints, leading to their multiplication and the body's reaction to these organisms and their toxins. These infections are usually caused by bacteria and can affect people of all ages. Septic arthritis, also known as infectious arthritis, is a painful infection of the joint that can occur when bacteria spread through the bloodstream or when germs enter through a penetrating injury. Another type of musculoskeletal infection is cellulitis, a common bacterial infection of the skin and underlying soft tissues that occurs when bacteria enter through a break in the skin.
In addition to viral infections, certain medications and drugs can also cause temporary muscle damage. This is known as drug-induced myopathies, and it can sometimes resemble myositis. Statins, which are used to lower cholesterol levels, are the most common drugs associated with this condition. Stopping the drug treatment typically leads to an improvement in symptoms, but in some cases, the symptoms may persist even after discontinuing the medication.
