Fungal Infections: Unseen Cause Of Muscle Pain

can a fungal infection cause muscle pain

Fungal infections are typically harmless, but certain types can cause serious infections and lead to sepsis. A fungal infection in the lungs, for example, may cause coughing, fever, chest pain, and muscle aches. In rare cases, fungi can cause myositis, a group of conditions that cause inflammation in muscles, leading to muscle weakness, swelling, and pain. Candida, a common cause of fungal infections, can lead to painful oral thrush, as well as joint pain if it enters the bloodstream. Additionally, people with suppressed immune systems are at risk of fungal arthritis, which can cause permanent joint damage.

Candida overgrowth

Candida is one of the most common causes of fungal infections in humans. Typically, healthy bacteria in the body keep Candida levels under control. However, if healthy bacteria levels are disrupted or the immune system is compromised, Candida can begin to overproduce, leading to health problems.

In women, Candida overgrowth can lead to vaginal candidiasis, or a vaginal yeast infection, which causes redness, swelling, itching, painful intercourse, and a thick, white discharge from the vagina. Women with Candida are at a high risk of developing these infections, which are generally indicated by pain during urination and sexual intercourse.

Candida can also cause genital and urinary tract infections, which may be indicated by pain in the pelvis, groin, or lower abdomen, pain during urination, and a frequent urge to urinate. Urinary tract infections caused by Candida are most common in older adults and hospitalised or immunocompromised individuals.

Additionally, Candida overgrowth can cause skin fungal infections, such as athlete's foot or toenail fungus, which can result in itching and a visible rash. If left untreated, Candida can enter the bloodstream and spread throughout the body, potentially causing bone and joint infections. Candida arthritis is associated with pain, stiffness, and swelling in the joints, typically affecting the hips and knees.

While Candida die-off, or the treatment of Candida infections, can be painful and uncomfortable, it is not usually dangerous. This process may cause muscle pain, fever, and headaches.

Fungal arthritis

While fungal infections are not a common cause of muscle pain, they can lead to myositis, which is a group of conditions that cause inflammation in muscles. Myositis can be caused by viruses, bacteria, fungi, or other organisms attacking muscle tissue directly or releasing substances that damage muscle fibres.

People with weakened immune systems who travel or live in areas where fungi are common are more susceptible to most causes of fungal arthritis. Conditions that weaken the immune system include severely low white blood counts (neutropenia), HIV infection, injection drug abuse, and chronic cortisone medication.

The diagnosis of fungal arthritis can be challenging due to the insidious onset of the disease and the lack of characteristic findings. Typical stains and smears used for fungal identification may fail to identify the organism, and routine cultures are often non-diagnostic. However, the demonstration of fungi on synovial, bone, or tissue culture and biopsy can be more indicative of an actual infection. Blood tests, plain X-ray images, CAT scanning, and MRI scanning can also be used to determine the character and extent of joint damage. Ultimately, joint fluid is aspirated from the joint and analysed in a laboratory to culture the precise fungal organism and establish the diagnosis.

The treatment of fungal arthritis involves the use of antibiotics directed against the precise fungal microbe causing the joint infection. Adequate drainage of the infected joint is an essential part of the treatment and generally requires orthopedic surgical procedures. Fungal arthritis is considered a medical emergency, and early diagnosis and treatment are recommended to improve survival rates.

Myositis

The diagnosis of myositis can be challenging, and it often involves a comprehensive process that includes taking a medical history, conducting a physical examination, and performing various diagnostic tests such as blood tests, muscle and skin biopsies, and imaging scans. The treatment for myositis depends on the underlying cause. When myositis is caused by a fungal infection, antifungal agents such as amphotericin B, azoles, or echinocandins are used. Early diagnosis and treatment of fungal myositis are crucial for improving survival rates, as mortality rates are high for this condition.

While there is no cure for myositis, treatments can help manage symptoms and slow its progression. Treatment options include medications, physical therapy, exercise, heat therapy, assistive devices, and rest. In severe cases, immunoglobulin therapy or other treatments to suppress the immune system's response may be offered. Working with a physical therapist can help individuals manage their condition by learning appropriate stretches and exercises to maintain muscle flexibility and strength, which can provide pain relief and improve overall well-being.

It is important to note that fungal infections, while capable of causing myositis, are uncommon due to the relative resistance of muscles to infection. However, when they do occur, they can lead to significant health challenges. Therefore, seeking medical attention and early diagnosis are essential to improving treatment outcomes for fungal myositis.

Myopathy

Myositis refers to a group of conditions that cause inflammation in muscles, but it can also refer to the muscle inflammation itself. Infectious myositis is defined as an infection of a skeletal muscle. While infectious myositis is uncommon, it can be caused by a broad range of bacterial, fungal, parasitic, and viral agents. The most common fungal causes of myositis are Candida spp., including C. tropicalis, C. krusei, and C. albicans.

In addition to myositis due to Candida infections, a triad of chronic mucocutaneous candidiasis, myositis, and thymoma has been described. Myopathy appears to be autoimmune in nature in these cases, rather than being due to the fungal pathogen itself. Cryptococcus neoformans infection may also rarely present with infectious myositis. Most infections with this organism are asymptomatic, but after the inhalation of the fungus, pulmonary, skin, or central nervous system (CNS) disease may occur.

Myositis caused by fungi usually presents as diffuse, multiple microabscesses, but larger, more discrete fungal abscesses can occur. The diagnosis of fungal myositis is suggested by the presence of concordant clinical signs and symptoms, a detailed medical and travel history, and laboratory data. Definitive diagnosis requires detecting the organism by specific laboratory testing, including serologies, histopathology, cultures, MRI, CT, or ultrasound.

Therapy for fungal myositis is with antifungal agents such as amphotericin B, an azole, or an echinocandin. Focal infectious collections should be surgically drained. Mortality rates are high, so early diagnosis and treatment are recommended to improve survival rates.

Sepsis

Although most fungi are harmless, certain types can cause serious fungal infections in some people. Fungi can enter the body through inhalation or direct contact with the skin, and they can infect any part of the body. Most fungal infections cause some discomfort, such as redness and itching, and they can usually be treated with over-the-counter or prescription medications. However, sometimes these skin infections do not heal and they worsen, possibly causing sepsis.

Fungal infections that cause sepsis are treated with intravenous anti-fungal drugs. Antibiotics are not used for fungal infections because they are not effective. Early diagnosis and treatment of fungal sepsis are critical, as delays in introducing appropriate antifungals are associated with increased mortality.

Fungal sepsis remains difficult to treat and is associated with a high mortality rate. Approximately 15-30% of the more than one million Americans who develop sepsis each year do not survive. However, researchers at the University of Bern have discovered a mechanism that helps a yeast fungus to spread more easily within the body, potentially opening up new therapeutic avenues for blood poisoning caused by yeast and other invasive fungal infections.
