Muscle inflammation in the legs can be caused by several factors, including injuries, infections, autoimmune conditions, and drug side effects. Myositis, an autoimmune disease, is a common cause of muscle inflammation, where the immune system attacks healthy muscle tissue, resulting in inflammation, swelling, pain, and weakness. Drug-induced myositis, caused by certain medications, can also lead to muscle inflammation. Intense exercise or physical trauma can also cause muscle inflammation and pain. Viral and bacterial infections may trigger inflammation throughout the body, including the legs. Additionally, chronic muscle diseases like myopathies can cause long-lasting inflammation and muscle damage. It is important to seek medical attention if muscle inflammation persists or is accompanied by other symptoms.

What You'll Learn
Intense exercise
DOMS usually starts about 12 hours after your workout and peaks around 48 hours post-workout. The soreness you feel is caused by your body repairing the microscopic tears in your muscles. This natural process makes your muscles stronger and more resilient over time.
There are several ways to treat muscle inflammation caused by intense exercise. Light basic stretches that you hold for a few seconds can help increase blood flow to sore areas without overstressing the muscles. Massage within 24 hours of intense exercise has also been found to help reduce soreness. Heat therapy, such as a warm bath or hot shower, is often preferred for post-exercise soreness as it increases blood flow to the affected area. Over-the-counter (OTC) creams and gels that contain menthol or capsaicin can also help ease muscle soreness and speed up recovery.
It is important to note that NSAIDs (nonsteroidal anti-inflammatory drugs), such as ibuprofen, may not be effective in reducing muscle soreness and may even be associated with higher levels of inflammation. According to the British Journal of Sports Medicine, inhibiting inflammation can negatively affect long-term tissue healing. Therefore, it is recommended to allow the natural inflammatory response to occur, as sore muscles indicate that your body is challenging and building up your muscles.

Viral or bacterial infections
Myalgia is the medical term for muscle pain, which has many causes. Viral and bacterial infections can trigger inflammation throughout the body. Many of these infections are temporary, like the common cold and flu, but some can be longer-lasting.
Myositis is a chronic inflammatory condition caused by the immune system attacking muscles throughout the body. It is characterized by episodes of inflammation that come and go over a long period, causing muscle weakness and pain. While the exact cause of myositis is unknown, it is often associated with viral infections, such as the common cold and influenza. In rare cases, bacterial infections, such as pyomyositis, can also trigger myositis. Pyomyositis is a bacterial infection that commonly affects the thigh muscles, causing pain, swelling, and fever. It is caused by bacteria such as Staphylococcus aureus and Group A Streptococcus.
In addition to viral and bacterial infections, myositis can also be caused by autoimmune conditions, drug side effects, and injuries. There is currently no cure for myositis, but treatments are available to manage symptoms and reduce their impact on daily life. These treatments include corticosteroids, immunosuppressants, and intravenous immunoglobulin.
Another form of myositis is sporadic inclusion body myositis (IBM), a degenerative disease that slowly weakens the muscles, usually starting in the legs and feet or arms and wrists. IBM typically affects individuals over the age of 50, causing muscle weakness and difficulty with grip and movement. While IBM is not commonly associated with significant inflammation, it can lead to muscle pain and stiffness.

Autoimmune conditions
Myositis is a chronic inflammatory condition caused by an autoimmune response, where the body's immune system attacks its own muscles. This can lead to muscle pain, weakness, and swelling, which can affect mobility and the ability to perform everyday activities. Myositis can affect different muscle groups throughout the body, including the legs and hips. While there is no cure for myositis, treatments such as corticosteroids, immunosuppressants, and intravenous immunoglobulin can help manage symptoms and bring the disease into remission.
Polymyositis is a rare form of myositis and an autoimmune disease that causes inflammation and weakness in the muscles. It is characterized by muscle pain, weakness, and trouble swallowing. Polymyositis can affect muscles throughout the body, including the hips and thighs, and typically occurs in adults aged 30 to 60. While there is no cure, treatments can help manage symptoms and prevent fatal complications.
Inclusion body myositis (IBM) is a degenerative form of myositis that slowly weakens the muscles over time, usually starting in the limbs, such as the legs and feet. IBM can make it difficult to grip objects and maintain balance, leading to an increased risk of falling. This form of myositis typically affects older individuals and progresses slowly over time.
Immune-mediated necrotizing myopathy, also known as necrotizing autoimmune myopathy, is a rare condition where muscle cells start to die, leading to muscle weakness and potential inflammation. This condition can affect muscles close to the center of the body, such as the thighs, hips, and shoulders. While the cause is unknown, it is believed to be triggered by an autoimmune reaction in individuals with certain genetic predispositions.
Idiopathic inflammatory myopathies are a group of autoimmune diseases that cause inflammation and weakness in the muscles and can also affect the skin and other organs. This group of conditions includes dermatomyositis, which is associated with skin changes and gastrointestinal symptoms in children. While the cause of idiopathic inflammatory myopathies is unknown, they are believed to be triggered by an autoimmune response and can have a genetic component.

Drug side effects
Aromatase inhibitors, used to treat breast cancer and other conditions, can cause joint pain and muscle inflammation, typically occurring months after starting the medication. Oral corticosteroids, commonly known as steroids, are another group of medications that can cause muscle inflammation as a side effect, especially when taken at high doses or for prolonged periods. This is known as steroid-induced myopathy and typically affects pelvic muscles, causing muscle weakness without pain.
Antibiotics such as fluoroquinolones, which are used to treat bacterial infections, have been associated with muscle pain and tendon inflammation (tendonitis). Isotretinoin, a treatment for severe acne, can also cause mild to severe joint and muscle pain in the later stages of treatment. Bisphosphonates, prescribed for osteoporosis, may cause mild muscle pain or inflammation, and blood pressure medications, particularly beta-blockers, have been linked to joint and back pain in a small percentage of patients.
Additionally, certain antiarrhythmic medications used to treat heart rhythm problems, such as amiodarone and procainamide, can interfere with muscle structures and function, leading to drug-induced myopathy. Colchicine, a medication for gout, may cause acute myopathy at high doses or with long-term use, resulting in progressive muscle weakness. It is important to note that muscle inflammation can be a side effect of various medications, and consulting a doctor is crucial to discuss alternative treatments or dosage adjustments.

Myositis
The diagnosis of myositis can be challenging, often involving a comprehensive process that includes a medical history review, physical examination, blood tests, and muscle biopsies. Treatment options vary depending on the underlying cause, with the primary goal being symptom management. Corticosteroids, immunosuppressants, and intravenous immunoglobulin are commonly used to treat myositis. Physical therapy and exercises are also recommended to maintain muscle flexibility and strength, aiding in pain reduction and improving overall functionality.
While there is no cure for myositis, proper treatment can induce remission, characterised by minimal or no inflammation in the muscles. However, it is important to note that most individuals with myositis will live with the condition for the rest of their lives. The condition can have serious implications, and without adequate treatment, it may lead to significant disability or even death in rare cases.
