Lupus is an autoimmune disease that affects people differently. However, muscle pain and weakness are common symptoms, with over half of lupus patients reporting muscle pain and/or weakness. Lupus can cause inflammation in the muscles, medically termed myositis, which usually affects the hips, thighs, shoulders, and upper arms. This inflammation can lead to muscle injury and weakness, making it difficult to perform everyday tasks such as standing up from a seated position. The pain and weakness associated with lupus are not due to overuse but are caused by the disease itself or as side effects of its treatments.

What You'll Learn
Lupus can cause muscle inflammation (myositis)
Lupus is an autoimmune disease that affects people in different ways. Most people with lupus experience problems with their joints, muscles, or bones. Lupus can cause muscle inflammation, known as myositis, which is characterised by muscle weakness. This can make it difficult to perform everyday tasks such as standing up from a seated position or raising your arms. Myositis typically affects the hips, thighs, shoulders, and upper arms.
Myositis is a less common manifestation of lupus, occurring in about 5%-10% of cases. It is characterised by inflammation of the muscles, resulting in pain and weakness. This pain may be more pronounced at night and can increase as the condition advances. Myositis is typically treated with higher doses of steroids, known as glucocorticoids or immunosuppressive drugs, and sometimes with disease-modifying antirheumatic drugs (DMARDs). However, prolonged use of high-dose steroids and glucocorticoids can lead to bone and muscle damage, so they are usually tapered off once the disease is under control.
The pain and weakness associated with lupus are not due to overuse but are caused by the disease itself or as side effects of medications used to treat lupus, such as steroids. Other treatments for lupus-related muscle pain include non-steroidal anti-inflammatory drugs (NSAIDs) like ibuprofen or naproxen sodium, joint rest, and physical therapy. It is important to note that too much rest can also lead to muscle weakness, so finding the right balance between rest and exercise is crucial. Walking, swimming, and other low-impact exercises are recommended as they improve fatigue, fitness, strength, and stamina without putting excessive strain on the joints.
Lupus can also cause joint pain (arthralgia) and inflammation, leading to conditions such as arthritis, tendonitis, and carpal tunnel syndrome. Joint problems related to lupus typically do not cause long-term damage and are less likely to result in permanent joint damage compared to rheumatoid arthritis. Additionally, lupus may cause narrowing of the blood vessels, increasing the risk of angina due to reduced blood flow to the heart muscle.

Lupus can cause muscle pain (myalgia)
Lupus is an autoimmune disease that affects people in different ways. Most people with lupus experience problems with their joints, muscles, or bones. Lupus can cause muscle pain, known as myalgia, which is a common symptom in lupus patients. The pain is usually felt in the upper arms and thighs, but it can also occur in other areas such as the hips, knees, or shoulders.
Myalgia refers to the aches and pains in the muscles caused by inflammation. This inflammation may be due to the disease itself or as a side effect of lupus treatments. For example, steroids used to treat lupus can cause muscle weakness, and high doses over a long period can lead to avascular necrosis (AVN), a condition that causes bone tissue death due to reduced blood flow. AVN can result in further muscle pain and spasms, joint stiffness, and limited movement.
Lupus patients may also experience muscle pain indirectly through associated rheumatologic conditions, such as fibromyalgia, which can cause widespread pain in the neck, shoulders, chest, hips, knees, and elbows. Additionally, stress, anxiety, and depression, which are common in people with lupus, can cause muscles to tense up, potentially worsening the pain.
Managing muscle pain in lupus involves working with a doctor to determine the cause and create a pain management plan. Nonsteroidal anti-inflammatory drugs (NSAIDs) are typically the first line of treatment for muscle pain, followed by low doses of steroids like prednisone if NSAIDs are ineffective. Alternative treatments like acupuncture can also be explored. Exercise, such as walking or swimming, is recommended to improve fitness and strength while minimizing joint strain.

Lupus treatments can cause muscle weakness
Lupus is an autoimmune disease that causes inflammation throughout the body. It affects different people in different ways, but most people with lupus experience problems with their joints, muscles, or bones. Lupus can cause joint pain, swelling, and stiffness, and can also affect the tendons and bursae, resulting in conditions like tendonitis and bursitis. Lupus can also cause muscle pain and inflammation, known as myalgia and myositis, respectively. Myositis is a less common complication of lupus and is characterised by muscle weakness, making it difficult to perform everyday tasks such as standing up from a chair or raising your arms.
While lupus itself can cause muscle pain and weakness, certain treatments for lupus can also contribute to these issues. Steroids, for example, are commonly prescribed to manage inflammation and pain associated with lupus. However, long-term use of high-dose steroids can lead to a condition called avascular necrosis (AVN). AVN occurs when there is insufficient blood flow to a part of the bone, resulting in pressure buildup and eventual bone collapse. Symptoms of AVN include pain in the hips, knees, or shoulders, followed by stiffness, muscle spasms, and limited movement. The risk of developing AVN is higher in people with lupus who take high doses of steroids for extended periods.
In addition to AVN, the use of steroids to treat lupus can directly cause muscle weakness. This side effect is usually reversible and tends to resolve when the medication is discontinued. Other medications used to treat lupus that may contribute to muscle weakness include prednisone, other corticosteroids, drugs to lower cholesterol, and hydroxychloroquine (Plaquenil®). It is important to consult with a physician before making any changes to prescription medications.
While lupus and its treatments can cause muscle weakness and pain, physical therapy and gentle exercises like walking and swimming can help strengthen muscles and improve stamina without putting excessive strain on the joints. Maintaining physical activity, with rest as needed, can help reduce muscle weakness associated with lupus and its treatments.

Lupus can cause joint pain and stiffness
Lupus is an autoimmune disease that affects people in different ways. However, most people with lupus experience problems with their joints, muscles, or bones. Lupus can cause joint pain (arthralgia) and inflammation in and around the joints, resulting in conditions like arthritis, tendonitis, and carpal tunnel syndrome.
Joint problems related to lupus usually do not cause long-term damage or change the shape of the joints. However, they can sometimes lead to serious issues. Joint pain is a common symptom in people with lupus, and it may interfere with their daily activities. The pain may originate in the joint itself (true arthritis) or the soft tissues around the joint (due to tendon or ligament issues).
Lupus arthritis typically affects joints farther from the body's core, such as fingers, wrists, elbows, knees, ankles, and toes. It causes stiffness, tenderness, warmth, and swelling in the joints. Lupus arthritis is less likely to result in permanent joint damage compared to rheumatoid arthritis.
Lupus can also cause tendonitis, which is inflammation of the tendons—the tissues connecting muscles to bones. Tendonitis usually affects joints like the elbows, fingers, and shoulders, causing pain and stiffness. In addition, lupus can lead to carpal tunnel syndrome, where inflammation puts pressure on the median nerve in the wrist, resulting in pain, tingling, and numbness in the hand and fingers.
Lupus often causes myalgia, or muscle aches and pains. It can also lead to myositis, or inflammation of the muscles, in more severe cases. Myositis typically affects the hips, thighs, shoulders, and upper arms and can cause muscle weakness, making it difficult to perform everyday tasks.

Lupus can cause bone issues, such as avascular necrosis (AVN)
Lupus is an autoimmune disease that affects different people in different ways. Most people with lupus experience problems with their joints, muscles, or bones. While lupus itself sometimes causes these issues, they can also be side effects of lupus treatments.
AVN is more likely to occur in individuals with lupus who take high doses of steroids to manage their condition, especially over a long period. In addition to steroid usage, other factors associated with AVN include trauma, alcohol abuse, sickle cell anemia, pancreatitis, and other conditions. While there is no effective medical treatment to reverse AVN, advanced cases may be treated with surgery, such as artificial joint replacement, to relieve pain and restore movement.
It is important to note that lupus also raises the risk of osteoporosis, a condition characterized by low bone density. Osteoporosis makes bones weak and more susceptible to fractures. Steroid medications used to treat lupus can contribute to bone loss, and the pain and fatigue associated with lupus can lead to inactivity, further increasing the risk of osteoporosis.
