What causes foot skin ulcers?

Foot skin ulcers may be what we call tinea pedis problem. Many people are prone to this problem, and different types have different treatment methods. If it is a blister type, you can apply isoflurane or clotrimazole anti-tinea lotion.

(1) Blister type: In the acute stage, the skin may develop acute reddening exudative blister lesions, which are mostly scattered. If there is erosion, secondary bacterial infection may often occur. When the blisters are small and not ruptured, you can apply Yikanyao or clotrimazole anti-tinea lotion or soak in 10% glacial acetic acid solution for 20 minutes, 2 to 3 times a day. If the blister is large, you can puncture it to release the blister fluid, and then apply compound leisuxin ointment or add moisture-relieving powder. If there is a secondary bacterial infection, soak it in 0.5% potassium permanganate solution and apply medicine after the infection is controlled.

(2) Immersion type: It often manifests as cracks in the webbed toes, accompanied by epidermal exfoliation and moist immersion, severe itching, and easy infection. You can use Moqiling medicine powder or compound Leisuoxin ointment, Kemei anti-tinea syrup, or Yikan anti-tinea syrup. After the exudate is reduced, use Moqiling ointment, Xuandi ointment, Miconazole ointment, etc. for treatment.

(3) Squamous keratotic type: Extensive desquamation occurs due to excessive keratinization of the soles and edges of the feet. Clusters of blisters often appear in the summer, while they become dry, cracked and painful in the winter. You can use compound benzoic acid ointment, clotrimazole ointment, or use it alternately with tinea lotion. In summer, you can soak in 10% glacial acetic acid solution once a night for about 15 minutes each time.

(4) Eczematoid tinea versicolor: Fungal infection of the feet causes clusters of itchy blister lesions on the sides and flexor sides of the fingers and palms, and even on the entire body. This is caused by the body's allergy to ringworm. Therefore, anti-allergic treatment should be given first, such as oral ketotifen and chlorpheniramine. In severe cases, 400 mg of triamcinolone suspension can be injected intramuscularly to suppress the occurrence of rash until the pathogenic lesions are controlled. At the same time, apply 3% boric acid water for wet compress or apply compound miconazole ointment, Fuqingshuang ointment, etc. After the eczema subsides, apply anti-tinea ointment such as Shuiqiling, Xuandi ointment, or Yikandao, Kemeidao, etc.

(5) Athlete’s foot infection: Athlete’s foot is extremely itchy and scratching may lead to bacterial infection, causing pustules, erysipelas or lymphangitis. At this time, antibiotics such as penicillin and gentamicin should be used for intramuscular or intravenous injection, and the feet should be soaked in 0.5% potassium permanganate solution and then applied with erythromycin ointment for treatment. After the inflammation subsides, external use of clotrimazole and tinea tinea syrup or Yikan tinea syrup can be used for treatment.
