Osteomyelitis
Symptoms of Osteomyelitis
Inacute osteomyelitis spread through the blood,infections of the leg and arm bones may cause fever and, sometimes days later, pain in the infected bone. The area over the bone may be sore, red, warm, and swollen, and movement may be painful. The person may lose weight and feel tired. When osteomyelitis results from infections in nearby soft tissues or direct invasion by an organism, the area over the bone swells and becomes painful. Abscesses may form in the surrounding tissue. These infections may not cause fever. Infection around an infected artificial joint or limb typically causes persistent pain in that area. Vertebral osteomyelitisusually develops gradually, causing persistent back pain and tenderness when touched. Pain worsens with movement and is not relieved by resting, applying heat, or taking pain relievers (analgesics). People often do not have fever, which is usually the most obvious sign of an infection. Pain may be continuous. Chronic osteomyelitismay develop if osteomyelitis is not treated successfully. It is a persistent infection that is very difficult to get rid of. Sometimes, chronic osteomyelitis is undetectable for a long time, causing no symptoms for months or years. More commonly, chronic osteomyelitis causes bone pain, recurring infections in the soft tissue over the bone, and constant or intermittent drainage of pus through the skin. Such drainage occurs when a passage (sinus tract) forms from the infected bone to the skin surface and pus drains through the sinus tract.
