Muscle pain is a common symptom of COVID-19, often occurring alongside other symptoms of the virus. The pain can be intense and may affect the entire body, including the legs, neck, and head. It can also manifest as joint pain in the wrists, ankles, shoulders, and knees. The muscle pain associated with COVID-19 is caused by inflammation and immune responses triggered by the infection. This inflammation is linked to an increase in cytokine production, which contributes to the pain and malaise experienced during the illness. In some cases, muscle pain may be the first symptom of COVID-19, appearing before respiratory symptoms such as a cough or shortness of breath. The severity and duration of muscle aches can vary, sometimes persisting for weeks, months, or even years after the initial infection.

What You'll Learn
Muscle pain is a common symptom of long COVID
Muscle pain is a common symptom of COVID-19. It is often one of the first symptoms to appear, sometimes even before respiratory symptoms like a cough and shortness of breath. This pain can be felt all over the body, with people reporting soreness in their legs, lower back, neck, head, biceps, hamstrings, back muscles, and left shoulder. The pain can feel like jolts or stings, or like the soreness experienced after exercising.
Muscle pain during illness is caused by inflammation and immune responses triggered by infections. When the body is fighting off an infection, it produces increased levels of cytokines, which contribute to inflammation and pain. In the case of COVID-19, the specific cytokines interleukin 1-beta (IL-1b), interleukin 6 (IL-6), and interleukin 17 (IL-17), as well as tumor necrosis factor-alpha (TNF-a), have been associated with muscle pain. This pain may be related to muscle fibre breakdown or rhabdomyolysis, which has been linked to high levels of IL-6 or TNF-a.
For those with long COVID, muscle pain can last for weeks, months, or even years after the initial infection. Ischemic myalgia, or muscle pain caused by a lack of blood flow to the tissues, is a common cause of muscle pain in long COVID. In addition to rest, healthcare providers may recommend over-the-counter pain medication or non-steroidal anti-inflammatory drugs (NSAIDs) to help relieve COVID-related muscle pain. Physical therapy can also be beneficial in relieving pain and healing muscle damage caused by the virus.

Muscle aches are caused by inflammation and immune responses
Muscle aches and pain can be caused by several factors, including injury, overuse, or stress on a muscle group. However, in the context of COVID-19, muscle aches are often a result of the body's immune response and inflammation.
When a person is infected with a virus like COVID-19, the immune system mounts a defence by sending antibodies to attack the virus and prevent its spread. This immune response can lead to inflammation throughout the body, causing muscle aches and pain. The inflammation is triggered by cytokines, small proteins produced by white blood cells, which can also lead to muscle fibre breakdown or rhabdomyolysis.
In addition to the immune response, the virus itself can directly cause muscle aches. Viral infections can attack important muscle linings and tissues, resulting in muscle pain and weakness. This pain can be similar to that experienced with mild arthritis, and it can persist even after the infection has cleared.
The muscle aches associated with COVID-19 can be quite severe and are considered one of the newer symptoms of the virus. They are not limited to a specific muscle group but are often experienced as full-body aches. These aches can be frustrating and challenging to manage, especially for those already dealing with joint or bone health issues.
To alleviate muscle aches caused by inflammation and the immune response, various treatments can be considered. Over-the-counter pain relievers, such as non-steroidal anti-inflammatory drugs (NSAIDs) like ibuprofen, can help reduce inflammation and provide pain relief. Rest, gentle stretching, and massage therapy can also aid in relaxing sore muscles and speeding up recovery. It is important to note that while these measures can provide relief, addressing the underlying cause of the inflammation and immune response is crucial for long-term management.

Cytokines can intensify muscle pain as part of the immune response
Muscle pain is a common symptom of viral infections, including COVID-19. While the virus itself does not directly cause muscle pain, the body's immune response to the infection can result in this symptom. Specifically, the release of cytokines as part of the immune response can lead to muscle soreness and pain.
Cytokines are small secreted proteins that mediate cell interactions and communication. They are produced by various cell types, including B cells, T cells, macrophages, mast cells, neutrophils, basophils, and eosinophils, each playing a distinct role in the immune system. Cytokines help coordinate the immune response to infections by stimulating specific antigen-dependent responses and activating different cell types.
In the context of muscle pain associated with COVID-19, certain cytokines are particularly relevant. Interleukin 1-beta (IL-1b), interleukin-6 (IL-6), and tumor necrosis factor-alpha (TNF-a) have been implicated in muscle pain. High levels of IL-6 in muscle have been associated with pain and muscle fiber breakdown observed in some viral infections. In response to these cytokines, muscles produce elevated levels of prostaglandin E₂ (PGE₂), a lipid molecule linked to inflammation and pain.
Additionally, cytokine release syndrome (CRS) can occur when the immune system responds excessively to an infection or certain immunotherapy treatments. CRS, sometimes called a cytokine storm, results in a range of symptoms, including fever, nausea, fatigue, and body aches. This exaggerated immune response can be life-threatening and requires prompt treatment.
While the specific mechanisms linking cytokines to muscle pain are still being explored, it is clear that cytokines play a crucial role in the immune response and can contribute to the development of pathological pain states. Understanding the role of cytokines in pain management may lead to novel therapeutic approaches, such as harnessing endogenous anti-inflammatory signaling to modulate cytokine activity and provide relief from chronic pain conditions.

Muscle pain may result from the virus attacking muscles
Muscle pain is a common symptom of COVID-19, with about 86% of people diagnosed with the virus experiencing it. The pain is often the result of the body's immune response to the virus, which releases special proteins called cytokines that trigger inflammation and lead to muscle and joint aches. Interleukin-6 (IL-6), interleukin-1 (IL-1), and tumor necrosis factor-α (TNF-α) are examples of these cytokines.
The COVID-19 virus may also directly damage muscle tissue by attaching itself to muscle cells, resulting in muscle pain. This pain may be similar to that experienced with mild arthritis. In addition, the virus may cause muscle fiber breakdown or rhabdomyolysis, leading to muscle tears associated with high levels of IL-6 or TNF-a. In response to these cytokines, muscles produce elevated levels of prostaglandin E₂ (PGE₂), a lipid molecule associated with inflammation and pain.
Muscle pain may also be a result of a lack of oxygen to the muscles or body-wide inflammation caused by the virus. This inflammation can lead to muscle tissue damage, interfering with normal movement and strength. In some cases, muscle pain may be a sign of post-COVID syndrome, lasting for weeks, months, or even years after the initial infection clears.
While muscle pain is a common symptom of COVID-19, it can also be caused by other conditions or factors, such as cholesterol-lowering drugs, anemia, or myositis, an autoimmune disease characterized by inflammation and degeneration of muscle tissues.

Muscle pain can be treated with over-the-counter pain medication
Muscle pain is a common symptom of many viral infections, including COVID-19. It is caused by the immune system's response to the virus, rather than the virus itself. The good news is that muscle pain can often be treated with over-the-counter (OTC) pain medication.
OTC pain relievers are available without a prescription and can be purchased at your local pharmacy or convenience store. They come in the form of pills, liquids, and creams. These medications can help with acute pain, which is pain that has lasted less than a month and has a known cause, such as an injury or infection. They can also be used to manage chronic pain, which is pain lasting three months or more.
The two main types of OTC pain medicine are acetaminophen and nonsteroidal anti-inflammatory drugs (NSAIDs). Acetaminophen (Tylenol) helps block pain messages in the brain and is used to relieve mild to moderate pain. NSAIDs, on the other hand, work by reducing the level of chemicals involved in inflammation. Common NSAIDs include aspirin, ibuprofen (Advil, Motrin), and naproxen (Aleve). NSAIDs are often recommended for pain with swelling and inflammation, while acetaminophen may be a better choice for those with existing kidney or heart problems as it tends to have fewer risks.
It is important to note that OTC pain relievers can interact with prescription drugs and other medications, so it is always recommended to consult your doctor or healthcare provider before taking any new medication. They can help determine if OTC medication is right for you and ensure there are no contraindications with your existing prescriptions. Additionally, always read the labels and instructions closely and use the lowest effective dose to help lower the risk of side effects.
