Frequently asked questions
Is osteomyelitis dangerous?
It can be, if untreated. Early antibiotics and, when needed, surgery usually control the infection and prevent lasting bone damage.
Why are diabetics at higher risk?
Poor circulation and nerve damage in diabetes lead to foot wounds that heal slowly, allowing infection to reach the bone.
