Skin Infection

Skin Infection

A skin infection occurs when bacteria, fungi, viruses, or parasites enter or overgrow on the skin. Feet are especially vulnerable because they are often enclosed in warm, moist environments that support microbial growth.

Why Skin Infections Occur

• Cracks, cuts, breaks in the skin or blister

• Excess moisture from sweating or tight footwear

• Fungal overgrowth (e.g., athlete’s foot)

• Bacterial entry through damaged or softened skin

• Poor circulation or reduced immune response

• Friction or pressure from footwear that weakens the skin barrier

Common Signs of a Skin Infection

• Redness or darker discoloration depending on skin tone

• Swelling or warmth

• Pain or tenderness

• Itching or burning

• Fluid‑filled blisters or oozing ( different colour )

• Scaling or peeling skin

• Unpleasant odour

• Cracks or fissures that worsen over time

When Skin Infections Need Care

A skin infection should be assessed or treated when it:

• Spreads or becomes more painful

• Produces pus, increased warmth, or swelling

• Leads to open wounds or bleeding

• Causes reduced sensation, numbness, or difficulty walking

• Does not improve with basic home care

• Occurs in people with diabetes or poor circulation

• May require antibiotics, which must be prescribed by a GP if a bacterial infection is suspected

• Persists despite treatment — in these cases, a swab or culture may be needed to identify the organism and guide stronger medication

• Produces significant pus or drainage, which may require special dressings depending on the amount and type of discharge

High‑Risk Situations

Persistent or worsening infections should be taken seriously because they can:

• Spread deeper into tissues

• Lead to systemic infection

• In severe cases, contribute to loss of limb if left untreated

• Affect underlying structures — if the infection is prolonged or located close to bone, an X‑ray may be needed to ensure it has not reached the bone

Management & Natural Support

• Professional assessment by a podiatrist when needed

• Keeping the feet clean and dry

• Salt‑water (saline) foot soaks(daily 10-15 min) to help cleanse the skin

• Applying betadine and proper dressing if there is puss

• Vinegar foot soaks may support fungal management in future days.

• Avoiding barefoot walking in communal areas

• Wearing breathable footwear and moisture‑wicking socks
