Muscle pain is a common symptom of COVID-19, with an estimated 86% of people diagnosed with the virus experiencing it. The pain typically lasts for about two weeks, but it can persist for months in people with long COVID. In such cases, the pain often takes on different characteristics and requires different management approaches compared to acute COVID muscle symptoms. While the exact mechanisms are not fully understood, several factors, including inflammation, lack of oxygen to the muscles, and direct viral attack on muscle cells, are believed to contribute to COVID-associated muscle pain.

What You'll Learn
Muscle pain from inflammation
Muscle pain is a common symptom of COVID-19. It can be caused by body-wide inflammation triggered by the immune system's response to the virus, or by the virus attacking the muscles directly. This is known as myalgia, and it can affect the entire body, with the most common areas of pain being the legs, neck, and head.
When the immune system detects the virus, it releases proteins called cytokines, which trigger inflammation and can lead to muscle and joint aches. This inflammation can cause pain and weakness in the muscles, and it can come and go over time. In addition to inflammation, COVID-19 can directly damage muscle tissue by attaching itself to muscle cells, resulting in more severe and long-lasting muscle pain. This combination of inflammation and direct viral attack creates a dual mechanism of muscle pain that can be challenging to treat.
For those with long COVID, muscle pain can persist for weeks or months after the initial infection. This pain often takes on different characteristics than the acute phase pain and may be more challenging to treat. It can be unpredictable, fluctuating in intensity and location without apparent triggers, making it difficult for patients to manage their symptoms and plan activities. The chronic nature of long COVID muscle pain may require comprehensive rehabilitation programs that address both the physical symptoms and the functional limitations that develop over time.
There are various treatments available to help manage muscle pain caused by inflammation and COVID-19. These include physical therapy, self-care strategies such as pain relievers, stretching, and the RICE method (rest, ice, compression, and elevation). Massage, heat therapy, and cold therapy can also help relieve muscle tension and soreness. In addition, over-the-counter medications like NSAIDs (nonsteroidal anti-inflammatory drugs) can reduce inflammation and provide pain relief.

Muscle pain from lack of blood flow
Muscle pain is a common symptom of COVID-19. It is caused by body-wide inflammation, the virus attacking the muscles, or a lack of oxygen to the muscles. In people with long COVID, a common cause of muscle pain is ischemic myalgia, which is the medical term for muscle pain from a lack of blood flow to the tissues. This type of pain can be challenging to treat because it involves ongoing circulation problems rather than just residual inflammation.
Poor circulation, or blood flow problems, can cause muscle pain. This can be due to various conditions, including obesity, diabetes, heart conditions, and arterial issues. For example, peripheral artery disease is a common condition that causes a narrowing of the arteries, restricting blood flow to the arms and legs. This can lead to muscle pain during exercise when the muscles are not getting enough oxygen and nutrients to function properly.
Other conditions that can cause poor circulation and muscle pain include Raynaud's disease, in which blood vessels in the toes and fingers narrow when stressed or cold, and deep vein thrombosis, where a blood clot forms in the leg, reducing blood flow. Smoking, high blood pressure, and high cholesterol can also contribute to poor circulation and muscle pain.
To improve poor circulation and alleviate muscle pain, it is recommended to exercise regularly, manage weight, eat a healthy and varied diet, and seek treatment for any underlying conditions. In some cases, medication or surgery may be necessary to improve blood flow and relieve pain.
While muscle pain is a common symptom of COVID-19, it is important to note that muscle pain can also be caused by various other conditions and should not be automatically attributed to COVID-19 without proper medical diagnosis.

Muscle pain from lack of oxygen
Muscle pain is a common symptom of COVID-19. The virus triggers body-wide inflammation, which can lead to muscle and joint aches. In some cases, COVID-19 can also directly damage muscle tissue by attaching itself to muscle cells, resulting in more severe and long-lasting muscle pain. This pain may persist for weeks or months after the initial infection, particularly in those with long COVID.
Lack of oxygen to the muscles can also cause muscle pain. This can occur when there is inadequate blood flow to the muscles, a condition known as ischemic myalgia. Ischemic myalgia is a common cause of muscle pain in people with long COVID. The reduced blood flow can be due to constricted blood vessels or the formation of blood clots, which decrease the blood's ability to carry oxygen.
Peripheral artery disease (PAD) is a common disorder that affects the legs. It is caused by a narrowing of the arteries in the limbs, which restricts blood flow and oxygen delivery to the leg muscles. This can result in pain, achiness, fatigue, burning, or discomfort in the muscles of the feet, calves, or thighs, particularly during exercise or other physical activities. PAD is most common in men over 50, but it can also affect women.
Smoking is a risk factor for PAD as it narrows the arteries and decreases the blood's oxygen-carrying capacity. Other risk factors include high cholesterol, diabetes, and being overweight. Treatment for PAD focuses on lowering the risk of vascular disease, improving circulation, and managing pain. In severe cases, surgery may be required to open blocked blood vessels or reroute the blood supply.
While muscle pain from COVID-19 can be challenging to treat due to its unpredictable nature and dual mechanism of inflammation and direct viral attack, most patients experience a complete resolution of muscle symptoms within several weeks, especially with early implementation of appropriate management strategies. Physical therapy, stretching, and the RICE method can help relieve pain and heal muscle damage caused by COVID-19 or lack of oxygen to the muscles.

Muscle pain from direct viral attack
Muscle pain is one of the most common symptoms of COVID-19. It can affect the entire body, but the legs, neck, and head are the most commonly affected areas. The pain can be deep and aching, making it difficult to walk or stand for extended periods.
COVID-19 can cause muscle pain through body-wide inflammation, a lack of oxygen to the muscles, or by directly attacking the muscles. When the immune system detects the virus, it releases proteins called cytokines, which trigger inflammation and can lead to muscle pain. In some cases, an oversupply of cytokines can cause excessive inflammation, resulting in muscle pain and weakness. This is known as a "cytokine storm".
However, medical observations have revealed that COVID-19 can also directly target and damage muscle tissue. The virus attaches to muscle cells, causing cellular damage that contributes to the pain and weakness many patients experience. This direct muscle invasion is unusual compared to other respiratory viruses. The combination of inflammatory damage and direct viral attack creates a dual mechanism of muscle pain that can be challenging to treat with traditional pain management approaches.
The muscle pain caused by COVID-19 can be long-lasting and may persist even after other symptoms have resolved. In people with long COVID, muscle pain can take on different characteristics and may be more challenging to treat. This type of pain is often referred to as ischemic myalgia, resulting from inadequate blood flow to the muscle tissues. It can fluctuate in intensity and location, making it difficult for patients to manage their symptoms and plan their activities.

Muscle pain in long COVID
Muscle pain is a common symptom of COVID-19. It can affect the entire body, but people with COVID most commonly experience muscle pain in their legs, neck, and head. The medical term for muscle pain resulting from a lack of blood flow to the tissues is ischemic myalgia, which is a common cause of muscle pain in people with long COVID.
COVID-19 can cause muscle pain through several mechanisms. Firstly, the virus triggers body-wide inflammation, which can lead to muscle aches and joint pain. This inflammation is a result of the immune system's response to the virus. When the immune system detects COVID-19, it releases cytokines, which are special proteins that trigger inflammation. Examples of these cytokines include interleukin-6 (IL-6), interleukin-1 (IL-1), and tumour necrosis factor-α (TNF-α).
Secondly, COVID-19 can directly damage muscle tissue. The virus has the ability to attach itself to muscle cells, causing cellular damage that contributes to the pain and weakness experienced by patients during their illness. This direct viral attack on muscle cells is a significant difference from how other respiratory viruses typically affect the body. The combination of inflammatory damage and direct viral attack creates a dual mechanism of muscle pain that can be challenging to treat.
In people with long COVID, muscle pain can persist for weeks or months after the initial infection. This pain often takes on different characteristics than the acute phase pain and can be more challenging to treat. It may require comprehensive rehabilitation programs that address both the physical symptoms and the functional limitations that develop over time. The unpredictability of long COVID muscle pain is another layer of complexity, with symptoms fluctuating in intensity and location without apparent triggers.
If you are experiencing muscle pain after a COVID-19 infection, it is important to seek medical advice. A doctor may refer you to a physical therapist who can help you develop a plan to relieve pain and heal muscle damage. Physical activity and rehabilitation programs are important ways to lessen muscle pain, especially for people with long COVID. Testing is the most reliable method for confirming COVID-19 as the cause of muscle pain.
