Lupus is an autoimmune disease that causes the immune system to attack the body's organs and tissues, resulting in inflammation and damage. This can lead to a range of symptoms, including joint pain, muscle pain, and weakness. While lupus itself can cause these issues, they can also be side effects of treatments for the disease, such as steroids, which can cause muscle weakness and increase the risk of avascular necrosis (AVN), a condition that weakens bones. Lupus can also cause myositis, or inflammation in the muscles, which can lead to muscle weakness and atrophy. Therefore, lupus and its treatments can contribute to muscle wasting.

What You'll Learn
Lupus and muscle inflammation (myositis)
Lupus is an autoimmune disease, which means it causes the immune system to attack the body's own tissues and organs. Lupus can affect the skin, joints, blood, and organs like the kidneys, lungs, and heart. Lupus arthritis most often affects joints that are farther from the middle of the body, like fingers, wrists, elbows, knees, ankles, and toes.
Lupus can also cause muscle inflammation (myositis), which is a disease that makes your immune system attack your muscles. Myositis is a type of myopathy, a general term for diseases that affect the muscles connected to bones. Myositis usually affects the muscles used for movement, including the arms, shoulders, legs, hips, abdomen, and spine. Lupus myositis can cause muscle weakness, making it difficult to perform everyday tasks such as standing up from a chair or raising your arms. It can also lead to skin problems and muscle pain.
Myositis can be caused by various factors, including injury, infection, or an autoimmune disease like lupus. While it is uncommon for individuals to have both lupus and myositis simultaneously, it is possible for there to be overlap between the two conditions. Myositis associated with lupus can weaken the muscles in the neck, shoulders, arms, upper pelvis, and thighs. In its early stages, this muscle weakness can make it challenging to rise from a seated position or climb stairs. As the condition progresses, individuals may struggle with tasks such as combing their hair, placing objects on a shelf, or getting out of a bathtub.
There is currently no cure for myositis, but treatments are available to manage symptoms and reduce disease activity. Typical treatments include corticosteroids, immunosuppressants, and intravenous immunoglobulin. Physical therapy and exercises like stretching can also help strengthen affected muscles and reduce pain and stiffness.
It is important to note that medications used to treat lupus, such as steroids and other corticosteroids, can also cause muscle weakness as a side effect. This side effect usually resolves when the medication is discontinued, but it is crucial to consult a doctor before making any changes to prescribed medications.

Lupus treatment and muscle weakness
Lupus is an autoimmune disease that causes the immune system to attack organs and tissue throughout the body. It can affect the skin, joints, blood, and organs like the kidneys, lungs, and heart. Lupus affects everyone differently, and symptoms can vary in severity.
Lupus can cause muscle pain and weakness, which may be due to inflammation or a side effect of medication. The most common symptom of myositis (inflammation of the muscles) is muscle weakness. Myositis usually affects the hips, thighs, shoulders, and upper arms. In the early stages, loss of strength in these muscles can make it difficult to rise from a chair or climb stairs. Lupus can also cause joint pain (arthralgia) and inflammation, resulting in problems like arthritis, tendonitis, and carpal tunnel syndrome.
If you are experiencing muscle weakness and are taking any prescription drugs, consult with your physician before changing how you take any medication. Your doctor can run lab tests that measure muscle enzymes, review your medications to determine the underlying cause of your muscle weakness, and adjust your medication accordingly.
To treat muscle weakness, your doctor may refer you to a rheumatologist, who can develop a physical activity plan to help strengthen your muscles. They may also refer you to a physical therapist, who can develop and supervise an exercise program to keep your muscles strong.
In addition to medical treatment, making lifestyle changes may prevent or ease lupus symptoms. Eating foods with plenty of calcium and vitamin D may help lower your risk of osteoporosis and avascular necrosis (AVN), a condition that causes bone tissue to die due to a lack of blood flow.

Lupus arthritis and joint pain
Lupus is an autoimmune disease, which causes the immune system to attack the body's own healthy tissues. This can include the joints, causing arthritis and joint pain. Lupus arthritis is caused by inflammation of the lining of the joint, known as synovitis, which leads to swelling, tenderness, and stiffness. Lupus arthritis usually affects joints further from the middle of the body, such as fingers, wrists, elbows, knees, ankles, and toes.
Lupus arthritis is distinct from other forms of arthritis, such as rheumatoid arthritis (RA), which can cause bone erosion. Lupus arthritis rarely causes bone erosions and is less likely to result in permanent joint damage. Symptoms of lupus arthritis include shorter periods of morning stiffness, less swelling, and shorter durations, usually lasting a few days. The symptoms may also migrate from one joint to another. In some cases, lupus arthritis can cause significant deformities, such as the misalignment of bones in the fingers.
Joint pain is a common symptom of lupus, with over 90% of people with lupus experiencing it at some point during their illness. It is often the first symptom that leads people to seek medical attention. Lupus joint pain can be treated with nonsteroidal anti-inflammatory drugs (NSAIDs), such as naproxen or ibuprofen. Antimalarial medications, like hydroxychloroquine, are also used to improve joint symptoms. Glucocorticoids are "miracle" drugs that work quickly to control inflammation and pain in lupus-related arthritis. However, prolonged use of high doses of glucocorticoids can cause bone and muscle damage. Therefore, they are typically used at low doses or tapered off once the disease is under control.
Lupus can also cause muscle pain (myalgia) and inflammation (myositis), resulting in muscle weakness. Myositis associated with lupus can weaken the muscles in the neck, shoulders, arms, upper pelvis, and thighs. This can make it difficult to perform everyday tasks, such as rising from a chair or lifting objects. Certain medications used to treat lupus, such as steroids and prednisone, can also cause muscle weakness. Additionally, lupus raises the risk of osteoporosis, a condition that weakens the bones and increases the likelihood of fractures.

Lupus and avascular necrosis (AVN)
Lupus is an autoimmune disease that causes the immune system to attack the body's organs and tissues, including the skin, joints, blood, and organs like the kidneys, lungs, and heart. Lupus affects everyone differently, and symptoms can vary in severity and combination. They can also come and go in waves, known as flare-ups, which can sometimes be severe enough to disrupt daily routines.
Lupus can cause joint pain and inflammation, resulting in problems like arthritis, tendonitis, and carpal tunnel syndrome. It can also lead to muscle pain and weakness, especially during flare-ups. This muscle weakness can make it difficult to perform everyday tasks such as standing up from a chair or raising your arms.
Avascular necrosis (AVN) is a rare complication of systemic lupus erythematosus (SLE) that can develop from the disease or its treatment. It is characterized by reduced blood flow and increased pressure within a portion of the bone, leading to bone weakening and, eventually, bone surface collapse. The most common symptoms of AVN include pain in the hips, knees, or shoulders, followed by stiffness, muscle spasms, and limited movement in the affected joints.
AVN is often associated with long-term use of high doses of corticosteroids, which are commonly prescribed to treat lupus. While the causes of AVN are not fully understood, studies have found that daily corticosteroid usage, high-dose corticosteroid therapy, and total daily steroid dosage were significantly higher in patients with AVN than in those without. Other factors that may contribute to AVN include hyperlipidemia, osteoporosis, proteinuria, and cushingoid body habitus.
While there is currently no effective medical treatment to reverse AVN, severe cases may require surgery, including artificial joint replacement, to help relieve pain and improve mobility.

Lupus and muscle pain
Lupus is an autoimmune disease, which means it causes the immune system to attack the body's own tissue, including muscles, joints, and connective tissue. The disease affects people differently, but 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 problems like arthritis, tendonitis, and carpal tunnel syndrome. Joint problems related to lupus usually do not cause long-term damage. Lupus arthritis most often affects joints farther from the middle of the body, such as fingers, wrists, elbows, knees, ankles, and toes.
Lupus often causes myalgia, or muscle pain and aches. It can also cause myositis, or inflammation in the muscles, usually in the hips, thighs, shoulders, and upper arms. The most common symptom of myositis is muscle weakness, which can make it difficult to perform everyday tasks like standing up from a chair or raising your arms.
Medications used to treat lupus, such as steroids, can also cause muscle weakness. Additionally, lupus raises the risk of osteoporosis, a bone disease that weakens the bones and makes them more susceptible to breaking. Avascular necrosis (AVN) is another condition associated with lupus, where bone tissue dies due to insufficient blood flow, leading to pressure buildup and bone weakening.
While lupus can cause muscle pain and weakness, it is important to note that the impact can vary among individuals. Seeking medical advice and working with healthcare professionals is crucial to understanding and managing the specific effects of lupus on the body.
