What Causes Myositis?

Rhabdomyolysis

Rhabdomyolysis is a serious condition that stems from an indirect or direct muscle injury. When the muscle is injured, the muscle fibers die. Instead of healing like an injury is meant to, the dead fibers release their contents into a patient's bloodstream. In serious cases, the sudden flood of toxicity can lead to kidney failure. From there, if a patient doesn't receive emergency medical treatment, they could die. With that said, the outcome tends to be positive for patients who receive timely medical care. The syndrome is difficult to categorize in terms of symptoms, because there's no telling what parts of the body will be affected. It's most common for patients to experience muscle pain in their lower back, thighs, or shoulders, since the dead muscle fibers are causing inflammation. They may also experience impaired mobility and muscle weakness, along with brown or dark red urine.
