What should be done if an elderly person's foot wound won't heal?

In general, elderly individuals may experience non-healing foot ulcers due to factors such as low immunity, poor blood circulation, athlete's foot (tinea pedis), lower extremity varicose veins, and rheumatoid arthritis. Treatment under medical guidance may include general supportive measures and medication. Specific analyses are as follows:

1. Low Immunity

Weakened immune function in the elderly makes wounds more susceptible to pathogens such as bacteria and fungi, leading to infections that further impair healing. It is important to maintain good nutrition, keep wounds clean and dry, and avoid exposure to sources of infection.

2. Poor Blood Circulation

With aging, blood vessels lose elasticity, and conditions such as atherosclerosis or thrombosis may further impair blood flow to the lower limbs. This reduces oxygen and nutrient delivery to the wound site, delaying healing. Regular moderate exercise can help improve circulation.

3. Athlete’s Foot (Tinea Pedis)

Athlete’s foot can result from fungal infections, moist environments, or lack of ventilation. Fungal infections compromise the skin’s protective barrier, causing skin breakdown and interfering with wound healing, potentially leading to the symptoms described. Pain, redness, and swelling may also occur. Treatment should be guided by a physician and may include topical antifungal medications such as miconazole nitrate cream, terbinafine hydrochloride cream, or bifonazole solution.

4. Lower Extremity Varicose Veins

Varicose veins are often related to impaired venous valve function. These veins disrupt normal blood circulation in the legs, leading to local hypoxia and inadequate nutrient supply, which delays wound healing. Symptoms may include hardened, dry skin around the ulcer. Patients should follow medical advice and may use medications such as diosmin tablets, Mailuoning granules, or ibuprofen sustained-release capsules.

5. Rheumatoid Arthritis

Rheumatoid arthritis may be triggered by autoimmune dysfunction, genetic factors, or infections. This condition disrupts immune system balance, leading to immune dysregulation and reduced ability to combat infections, thereby impairing wound healing. Symptoms may include general fatigue and low-grade fever. Medications such as methotrexate tablets, leflunomide tablets, and hydroxychloroquine sulfate tablets should be used as directed by a physician.

Elderly individuals should maintain regular physical activity, eat a balanced diet to strengthen their constitution, and practice good personal hygiene—especially keeping the feet clean and dry—to prevent foot problems and promote overall health.
