A bone infection, also known as osteomyelitis, occurs when bacteria or fungi invade the bone tissue. This can happen through an open wound, surgery, or the spread of infection from nearby tissues. Symptoms may include pain, swelling, fever, and redness around the affected area. Treatment typically involves antibiotics or antifungal medications to eliminate the infection. In some cases, surgery may be necessary to remove infected tissue or drain abscesses. Early diagnosis and treatment are crucial to prevent complications and preserve bone health.
