First of all, let’s look at the typology and precautions for tinea pedis: Tinea pedis (commonly known as foot fungus) is a dermatophyte infection between the toes, plantar, heel, and lateral edge of the foot, and is the most common superficial fungal disease that is widely prevalent throughout the world, with more onset in the south of China than in the north. It has a high incidence in summer and autumn, and often manifests itself as summer-heavy and winter-light or summer-onset and winter-healing. Tinea pedis mostly affects adults, and there is no significant difference in the proportion of men and women. The lesions tend to spread from one side to the opposite side. Tinea capitis can be divided into three types according to clinical characteristics: a. Blistering and scaling type It occurs between the fingers (toes), the palm, the plantar area and the side of the foot. The lesions start out as deep blisters of pinpoint size with clear fluid and thick, shiny walls that do not easily break down. Itching is obvious. The blisters dry up after several days, showing collar-like or flaky flaking, and the lesions keep spreading to the surrounding area, with flaking predominating when the disease is stable. Hyperkeratotic type Prevalent in the heel and palmoplantar area. Local dryness, keratin thickening at the lesions, surface roughness and flaking, texture deepening, prone to cracking and bleeding, lesions can also spread to the back of the foot. Generally no itching, painful when cracked. Third, the impregnated vesicle type Prevalent in the finger (toe) crevice, especially the 3rd to 4th and 4 to 5th finger (toe) between the common. The skin is white with impregnation, the surface is soft and easy to peel and reveal a flushed vesicular surface or even fissures. There are varying degrees of itching, secondary to bacterial infection when there is a foul odor. So, is itchy feet always tinea pedis? In practice, there are skin diseases that do behave very similarly to tinea pedis and are even difficult to identify. Therefore, in addition to the typical clinical symptoms, the diagnosis of tinea pedis also requires taking some skin exfoliations and examining them under a microscope, and if you see mycelium or spores of a specific shape of a typical pathogenic bacterium, then the diagnosis is basically clear. Some clinical manifestations also help to diagnose tinea capitis. Because it is an infectious disease, tinea capitis usually has an “inoculation” process, with lesions spreading from one side to the other. Therefore, ringworm tends to start on one side, meaning that you may start with a few small blisters on your left foot and find the same blisters on your right foot after a while. Because the fungus likes humidity, tinea capitis is more common in the summer heat and often starts in the toe or finger crevices and gradually progresses outward. In addition to the three types of manifestations mentioned above, tinea capitis is often accompanied by damage to the nails (onychomycosis). It is important to note that some eczema, psoriasis, and even second-stage syphilis can also manifest as some of the symptoms mentioned above, so it is best for non-professionals to seek medical attention in a regular hospital for these conditions and not to self-diagnose to avoid delaying the condition. The key to the successful treatment of tinea pedis is to adhere to the medication, the course of treatment usually takes 1 to 2 months, and attention should be paid to timely and thorough treatment of superficial fungal disease to eliminate the source of infection; ② Wear breathable shoes and socks to keep the feet dry; ③ Daily life should also avoid damage to the skin of the feet from acid and alkaline substances; ④ Do not share shoes and socks, bath tubs, foot basins and other household items; ⑤ Those with nail fungus should be treated at the same time (5) If you have nail fungus, you should treat nail fungus at the same time to avoid mutual infection. The last and very important point is that not all ringworm can be treated with dacrynic acid, especially vesicular ringworm, and using the wrong medicine can aggravate the rash, so it is important to seek medical attention in time to avoid delaying the condition.
