A burning sensation in the muscles is typically caused by the buildup of metabolites during intense exercise. It can also be caused by nerve damage, peripheral neuropathy, or an inability to absorb vitamin B12. In some cases, it may be a symptom of an infection, such as a UTI or cellulitis, or a more serious condition such as multiple sclerosis or neuralgia. It is important to seek medical attention if the burning sensation is persistent, spreads to other muscles, or is accompanied by other symptoms such as swelling or pain. While muscle burn during exercise is generally considered a positive indicator of muscle growth, it is important to be aware of potential underlying causes and when to seek medical advice.

What You'll Learn
Lactic acid buildup
A burning sensation in the muscles can be caused by various conditions, and a correct diagnosis is essential.
Lactic acid is a chemical produced by the body when cells break down carbohydrates for energy. It is a fuel source for cells during intense exercise and is also known as lactate. It was once believed that lactic acid buildup caused muscle soreness and burning after exercise. However, studies have debunked this myth, showing that lactic acid is quickly flushed out of the muscles and does not cause cell damage or pain.
The soreness experienced after intense physical activity is now understood to be caused by microtears in muscle fibres, which can be beneficial for muscle growth and strength. Additionally, the burning sensation during exercise is attributed to the buildup of hydrogen ions, which create an acidic environment in the cells. This buildup of hydrogen ions, along with other byproducts of muscular metabolism, is the true cause of the muscle burn.
While lactic acid itself does not cause muscle soreness or burning, a condition called lactic acidosis can occur due to a dangerous buildup of lactate in the blood. This condition is typically a result of decreased liver and kidney function, which impairs the body's ability to process lactate effectively. Lactic acidosis can be a serious complication, and it is important to address any concerns with a healthcare professional.
To summarize, lactic acid is not the primary cause of muscle burning sensations. While it is produced during intense exercise, it is quickly cleared by the body and does not lead to muscle pain. The burning feeling is instead caused by the accumulation of hydrogen ions and other metabolic byproducts. In rare cases, a buildup of lactate can lead to lactic acidosis, a serious condition that requires medical attention.

Muscle injury
A burning sensation in the muscles can be a symptom of nerve damage, which is referred to as peripheral neuropathy by the medical community. This is often caused by diabetes, but can also be caused by multiple sclerosis, neuralgia, radiculopathy, nutritional deficiencies, or other medical conditions.
Muscle strains, or pulled muscles, are a common type of muscle injury. They can be caused by a sudden, forceful movement, or by twisting, and they can also develop gradually due to overuse. Symptoms of a pulled muscle include soreness and tenderness, and the ability to locate the pain in one spot. In more severe cases, there may be a "'popping" sound or feeling, severe pain, bruising, and swelling.
If you suspect that you have a pulled muscle, it is important to follow the advice of a healthcare provider to ensure a smooth recovery. Most muscle strains can be treated at home, but severe tears may need medical care or even surgery. Minor strains should heal within a few weeks, while more moderate strains may take several weeks to months to heal. Severe strains can take four to six months to heal, even with surgery.
If you experience a persistent burning sensation, it is important to schedule an appointment with a doctor. They will likely perform a physical examination, ask about your pain, and may order diagnostic tests to identify the underlying cause. These tests may include blood or urine tests, imaging tests such as X-rays and CT scans, electromyography (EMG), nerve conduction velocity tests, nerve biopsies, and skin biopsies.

Nutritional deficiencies
A burning sensation in the muscles can be caused by a variety of factors, including nutritional deficiencies. Nutritional deficiencies can alter bodily functions and metabolic processes at the cellular level, and they can lead to pain and inflammation.
Vitamin D deficiency, for example, is linked to musculoskeletal pain and muscle hypersensitivity. This is due to the anti-inflammatory properties of vitamin D, which suggest that its deficiency could make tissues more susceptible to inflammation. Research has also shown that vitamin D deficiency is associated with sensory hyperinnervation, which can lead to increased neurogenic inflammation within muscles.
Vitamin B12 deficiency can also cause neurological pain and strange sensations such as tingling. This is because vitamin B12 is important for the myelin sheath, which protects the nerves. A lack of vitamin B12 can lead to fatigue, anorexia, and burning sensations.
Magnesium deficiency can result in muscle cramps, contractions, and abnormal heart rhythms. It is the most abundant mineral in the body and is required for over 300 biochemical reactions, including protein synthesis, muscle and nerve function, and bone health.
It is important to consult a doctor if you experience a persistent burning sensation, as they can perform diagnostic tests to identify the root cause and develop a personalised treatment plan.

Nerve damage
A burning sensation in the body can be caused by various conditions, and nerve issues are a common cause. This type of pain is called nerve pain or neuralgia, which is distinct from other types of pain. Neuralgia is often described as a shooting, stabbing, or burning pain. It is caused by damage to the nerves due to disease or injury. Neuralgia is not an illness in itself but a symptom of injury or a particular disorder.
There are several diagnostic tests to identify the root cause of burning sensations. These include electromyography (EMG) and nerve conduction studies (NCS) to assess nerve and muscle function. MRI and CT scans can also be used to produce detailed images of the brain and spine to identify structural problems. Blood tests can help evaluate nutrient deficiencies, immune disorders, and other underlying health issues. Evoked potential tests measure electrical activity in the brain and spinal cord, while a lumbar puncture (spinal tap) tests cerebrospinal fluid to diagnose conditions like multiple sclerosis.
There are several conditions related to nerve damage that can cause a burning sensation. These include:
- Central pain syndrome: Damage to the central nervous system (CNS), which includes the brain and spinal cord, can lead to chronic burning pain.
- Cervical spondylosis: Degeneration in the neck vertebrae can cause nerve compression, leading to chronic pain and burning in the neck or shoulders.
- Herniated disk: When a spinal disk presses on surrounding nerves, it can cause a burning or tingling pain radiating down the arms or legs.
- Mononeuropathy: Damage to a single nerve due to injury, compression, or inflammation, such as in carpal tunnel syndrome.
- Multiple sclerosis (MS): An immune-related disorder affecting the CNS, leading to burning, tingling, or muscle spasms.
- Peripheral neuropathy: Common in diabetes, it leads to burning, tingling, or numbness, especially in the hands and feet.
- Radiculopathy: A pinched nerve root in the spine, which may cause burning pain radiating from the back to the limbs.
It is important to seek medical advice if you experience a persistent burning sensation. A doctor will perform a physical examination, ask about your pain, and may order specific tests to identify the underlying cause. Treatment for nerve pain depends on the cause and may include lifestyle changes, medicines, and other treatments.

Underlying medical condition
A burning sensation in the muscles can be caused by underlying medical conditions. This can occur anywhere in the body, and a correct diagnosis is essential.
A burning sensation in the hands and feet may be a symptom of nerve damage, referred to as peripheral neuropathy. This is common in people with diabetes. A person with diabetes should consult a doctor if they experience such symptoms. Raynaud's phenomenon, which causes the small arteries in the hands and feet to spasm and close when exposed to cold, can also result in a burning sensation.
Neuralgia, or pain following nerve damage or infection, is another potential cause of a burning sensation. This often occurs in the face or neck. Multiple sclerosis, an immune-related disorder affecting the central nervous system, can also lead to burning, tingling, or muscle spasms.
Central pain syndrome, resulting from damage to the central nervous system, may lead to chronic burning pain. Cervical spondylosis, or degeneration of the neck vertebrae, can cause nerve compression, leading to chronic pain and a burning sensation in the neck or shoulders.
Chronic exertional compartment syndrome is a condition that affects the muscles and nerves during or after exercise, causing symptoms such as pain, swelling, aching, burning, or cramping in a limb, usually the lower limb. This syndrome warrants immediate medical attention to determine any underlying health conditions.
Additionally, nutritional deficiencies, such as a lack of vitamin B12 or folic acid, have been linked to burning sensations.
