What is osteomyelitis? Osteomyelitis is an infection of the bone, caused by bacteria or fungi. Symptoms include bone pain, swelling, fever, aches and pains, and headache. The infection may occur at areas near the bone where there was trauma, such as a skin ulcer, surgery, or other injuries. It can start at the bone and spread to surrounding areas, such as the skin, muscles or tendons. Having implanted devices such as a plate, rod or prosthesis can increase the risk of infection.
