M86.4: Chronic osteomyelitis with draining sinus
Chronic osteomyelitis with draining sinus is a long-term bone infection that typically develops after an injury, surgery, or when an infection from another part of the body spreads to the bone through the blood. With this particular form of osteomyelitis, a drainage passage, also known as a sinus, is formed from the site of the infection to the skin. This is the body's way of discharging the pus that builds up from the infection. Symptoms may include persistent bone pain, swelling, redness, and warmth at the infection site, as well as drainage of pus from a sore on the skin. This condition may also induce fever and malaise (a general feeling of unwell). Chronic osteomyelitis with draining sinus can be a complex condition to manage and it typically requires medical intervention to help control infection and alleviate symptoms.
