Athlete's foot and corns, although both are skin diseases, are quite different with many distinctions. First, athlete's foot is a fungal infection causing dermatophytosis, while corns are skin conditions formed by prolonged standing or chronic friction and pressure. Additionally, the treatment for athlete's foot involves antifungal medications, whereas corns can be treated with the application of corn ointments. It is advisable to wear loose and breathable shoes and maintain good personal hygiene. (Specific medications should be used under the guidance of a physician.)

The causes of athlete's foot

Athlete's foot is caused by a fungal infection, and while the cause of the disease is clear, the specific process of infection is complex. Casual habits such as wearing flip-flops recklessly, sharing foot basins at home with others who have athlete’s foot, soaking in public baths, swimming, or having pets at home, as pets often harbor fungi, can all potentially lead to the disease. Once the disease occurs, it is imperative to treat it early. Long-term use of antifungal creams, applied for at least one to two months continuously, is necessary to completely kill the deep-seated fungi and prevent recurrence of the condition. After recovery, it is also important to maintain proper dietary and lifestyle habits, avoid wearing flip-flops recklessly, and stay away from public baths and swimming pools.

What does it mean if there is fluid in athlete's foot?

Athlete's foot, also known as tinea pedis, commonly manifests in three types: vesicular, hyperkeratotic, and intertriginous. The vesicular type is characterized by blistering and scaling, typically occurring on the tips of the fingers, the palms, and the sides of the feet. Initially, the skin lesions appear as small, scattered blisters the size of a pinhead. The blister fluid is clear, and the blister walls are relatively thick. These blisters can cluster and merge to form larger blisters, eventually losing their walls to expose a honeycomb-like base and a raw, eroded surface. After several days, the blisters can dry out and flake off. As the condition progresses and exudation increases, it can develop into the intertriginous type, which primarily affects the web spaces between the fingers or toes. It is more common in people who sweat excessively, soak their feet in water, or wear rubber shoes for extended periods, particularly during the summer. The skin becomes soaked and appears whitish, with a soft surface that peels off easily, revealing a moist red eroded area with exudate, often accompanied by cracking and significant itching. When secondary bacterial infection occurs, there is typically an odor. If not promptly controlled, it can lead to secondary infections, producing pustules and ulcers, and may also lead to acute lymphangitis, lymphadenitis, cellulitis, or erysipelas. In severe or recurrent cases, it can also induce local eczematous changes and disseminated dermatophytosis.

Is infant thrush related to athlete's foot?

Infant thrush and athlete's foot are not highly related. Thrush is an oral infectious disease caused by Candida albicans infection, while athlete's foot is a local superficial skin fungal infection caused by fungi such as Trichophyton rubrum and Trichophyton mentagrophytes. The pathogens of the two are different and are not related. Thrush is a common oral infectious disease in infants and young children, mostly due to poor immune function in children, lack of oral hygiene, incomplete sterilization of bottles and pacifiers, or contact with children suffering from thrush.

The difference between smelly feet and athlete's foot

Athlete's foot is a disease caused by a fungal infection, characterized by being contagious and recurrent. Typically, after contracting athlete's foot, small blisters may appear on the foot, and these blisters can burst, possibly resulting in an unpleasant odor or foot odor. Additionally, wearing shoes for a long time that are tightly fitted and cause excessive foot sweating might also contribute to the condition. If it is merely foot odor, it is related to the fermentation of bacteria on the foot, such as wearing synthetic socks or excessive sweating of the feet, and infrequent foot washing. These factors can all cause foot odor, which is different from athlete's foot. Foot odor requires frequent washing with hot water, and it is advisable to avoid spicy and irritating foods. Treatment for athlete's foot involves the application of antifungal creams. Furthermore, foot odor is not contagious, whereas athlete's foot is contagious.

Does Huoxiang Zhengqi Water treat athlete's foot?

Huoxiang Zhengqi Water is generally used to treat summer colds, dizziness, fever, or diseases accompanied by cold symptoms. It has no special effect on treating athlete's foot. Athlete's foot is caused by fungal infections and is contagious and recurrent. For treating athlete's foot, it is best to use formal medications, otherwise, due to its high contagiousness, it might spread to family members. Currently, commonly used ointments include Naftifine Ketoconazole Cream or Nitrate Sertaconazole Cream, and the treatment usually requires a long course, at least persisting for more than a month. Or after the symptoms have completely disappeared, continue using it for about half a month more, which can generally cure it completely. Towels and basins for washing feet, used daily, must be separated from those of other family members to prevent cross-infection.
