⚡ Time is critical with serious foot infections. Delaying treatment can lead to sepsis, amputation, or death. When in doubt, seek immediate medical attention.
Bacterial infection of the skin and underlying tissues. Usually starts with a break in the skin.
Particularly dangerous due to neuropathy and poor circulation. Even mild infections can become serious quickly.
Infections that spread beyond the skin into deeper tissues, muscles, or bones.
Advanced diagnostic testing to identify the specific bacteria causing your infection and determine the most effective treatment.
Prescription antibiotics chosen based on culture results, ensuring the most effective treatment for your specific infection.
When necessary, surgical procedures to remove infected tissue, drain abscesses, or address underlying issues contributing to infection.
Treatment for a foot infection depends on its type and severity. Our board-certified podiatrists will assess your infection and recommend the most appropriate course of action.

Necrotizing fasciitis (flesh-eating bacteria) and gas gangrene are rare but life-threatening complications. People with diabetes are at especially high risk. Seek immediate medical attention if you suspect a serious foot infection.
Foot infection treatment depends on severity. Mild infections may be treated with oral antibiotics, wound cleaning, and rest. Serious infections may require IV antibiotics, surgical debridement (removal of dead tissue), drainage of abscesses, or hospitalization. Diabetic foot infections often need specialized wound care. A podiatrist can assess your infection and recommend the appropriate treatment.

Sepsis is a medical emergency — call 911 or go to the ER immediately if you suspect sepsis from a foot infection.
Go to the ER immediately if you have: fever above 101°F with chills, red streaking spreading up your leg, black or dead tissue on your foot, pus with foul odor, rapid heartbeat or difficulty breathing, confusion, or if you have diabetes and any foot wound that isn't healing.
