Manhattan Podiatry Group • Skin Infection Diagnosis, Wound Assessment & Clinical Care
Foot cellulitis is a bacterial infection of the deeper layers of skin and underlying soft tissue. It may develop when bacteria enter through cracked skin, a blister, a cut, an ingrown toenail, or a foot wound.
Infected skin often becomes red, warm, swollen, tender, and painful. Redness can spread over hours or days, sometimes accompanied by fever or chills. The infection requires timely medical evaluation because untreated cellulitis can spread and cause serious complications.
At Manhattan Podiatry Group, Dr. Mark Sharobeem, DPM, evaluates foot and ankle skin changes, looks for underlying wounds or entry points, and recommends treatment or escalation of care based on the severity of the infection.
Our practice is located at 55 Broadway, Suite 602, in Manhattan's Financial District. If you suspect cellulitis, seek a same-day medical assessment. For rapidly worsening symptoms or signs of severe illness, go to an emergency department.
Bacteria can enter through cuts, punctures, blisters, cracked skin between the toes, or an infected ingrown nail. Sometimes the opening is so small that it is difficult to see. Treating athlete's foot and caring for wounds can help reduce repeat infections.
An affected area may be red or discolored, hot to the touch, swollen, and sore. On darker skin, redness can be less noticeable. An expanding patch, fever, chills, or increasing tenderness warrants prompt medical assessment.
Diabetes, leg or foot swelling, poor circulation, chronic skin disease, previous cellulitis, and a weakened immune system can raise risk or complicate healing. Foot ulcers and reduced sensation make careful examination especially important.
A clinician generally diagnoses cellulitis by examining the skin, checking how far symptoms extend, and reviewing possible wounds, injuries, and underlying health conditions. Blood tests, cultures, or imaging may be appropriate when infection is severe, an abscess or deeper infection is suspected, or the diagnosis is uncertain.
Most uncomplicated cases can be treated with prescribed oral antibiotics. More serious infections may require hospital assessment and intravenous antibiotics. If an abscess is present, drainage may be necessary; infected ulcers or other entry points may also require wound care. The treatment plan depends on the examination and response to therapy.
Elevating the affected foot when practical and following the prescribed treatment may help with swelling and recovery. Complete antibiotics as directed and attend recommended follow-up. If symptoms worsen or fail to start improving within 24 to 48 hours of treatment, seek prompt reassessment.
Go to the emergency department for rapidly spreading redness, severe or disproportionate pain, fever with marked illness, confusion, faintness, purple or black skin changes, or concern for a deep infection. These symptoms can signal a potentially serious infection requiring urgent treatment.

Cellulitis needs prompt medical evaluation, even when symptoms seem mild. Seek emergency care if redness spreads rapidly, pain is severe, you have fever with significant illness, confusion, faintness, or skin that turns dark or purple. Severe infections can progress quickly.
Athlete's foot is a fungal infection that commonly causes itchy, peeling, or cracked skin, especially between the toes. Cellulitis is a bacterial infection that causes deeper skin inflammation with warmth, swelling, pain, and often spreading discoloration. Cracks from athlete's foot can provide an opening for bacteria.
Antibiotic choice depends on clinical findings, allergies, local resistance patterns, and whether an abscess or other complicating condition is present. A clinician may prescribe oral antibiotics for uncomplicated cellulitis; severe infections may require intravenous treatment in a hospital.
Pain, warmth, and swelling often begin improving within the first 24 to 48 hours after appropriate treatment, although visible skin changes may take longer to resolve. Some inflammation can initially appear worse. Contact a clinician promptly if you are deteriorating or not beginning to improve within 24 to 48 hours.
Yes. Diabetes, especially when associated with reduced sensation, poor circulation, or an open ulcer, can complicate foot infection and healing. Patients with diabetes and new foot redness, warmth, swelling, or an ulcer should seek prompt assessment.
Recurrence is possible, particularly when cracks between the toes, repeated wounds, chronic swelling, or other risk factors persist. Appropriate skin care, treating fungal infections, protecting the feet from injury, and managing underlying conditions can help reduce recurrence.
