What should I do if my feet are itchy with red spots

Most people are familiar with diseases, and most diseases have some obvious symptoms when they appear. The first type of disease is skin disease. Many people have itchy red spots on their feet due to some factors, but they don’t know how to treat this symptom. So, what should you do if you have itchy red spots on your feet?

First, what should you do if you have itchy red spots on your feet? The blisters of blister-type athlete's foot are distributed in groups or scattered on the soles and edges of the feet. Local skin flushing, and blisters and pustules may appear during secondary bacterial infection, which is more common in summer. Similar to the traditional Chinese medicine "snail blister". "Yi Zong Jin Jian" records: "...When first born, the shape is like a bean, with yellow blisters, stuffy and swollen, hard and painful, unable to touch the ground, and several blisters appear in succession. The skin is thick and difficult to break by itself, and after three or five blisters, it becomes wet and rotten; in severe cases, the feet are swollen, and there are alternating chills and fever..." This type of athlete's foot usually causes severe itching, and sometimes the blisters need to be scratched to provide relief. After long-term scratching, the skin becomes rough and thickened, and often develops into papular and scaly athlete's foot.

Second, this type is often an acute stage of athlete's foot, with a rapid onset, severe in summer and mild in winter. The primary lesions are mainly small blisters, which appear in groups or scattered, with thick walls and clear blister fluid, and are often located between the toes, the soles of the feet, and the sides of the feet. The blisters are located under the stratum corneum of the epidermis. Because the stratum corneum of the plantar part is thicker, the blister wall is not easily penetrated and there is no redness on the surrounding skin. If there is no secondary bacterial infection, the blister fluid will be absorbed on its own after a few days. After the blisters rupture, annular desquamation occurs and the skin lesions continue to expand in all directions. As the skin lesions continue to expand and spread, some small blisters may merge into large blisters. If secondary bacterial infection occurs, a red halo will appear around the blister and the blister fluid will become purulent and turbid. After the blister wall ruptures, local erosion or swelling occurs. At this time, if the inflammation is not controlled in time with improper medication, it may easily cause complications such as lymphangitis.

What should you do if you have itchy red spots on your feet? Many patients with tinea pedis panic and try to find a suitable medicine because of the unbearable itching. In fact, the treatment of tinea pedis is not to apply only one antifungal ointment from beginning to end, but to choose different medicines according to the blister type, thick skin type, erosion type, etc. The most important thing is to clean the wound and keep it dry before using the medicine, so that the effective ingredients of the medicine can reach the lesion directly. [2] Use "medicated blisters" for thick-skinned tinea pedis. Thick-skinned tinea pedis usually occurs on the heels, and is characterized by thick, dry skin that is easily peeled or cracked. This type of tinea pedis is difficult to penetrate by simply applying topical ointments. It is best to dissolve salicylic acid or other drugs in warm water and soak the skin to accelerate the softening of the stratum corneum and allow the drug to quickly reach the deep layers of the skin. Each soaking time is 10 to 15 minutes. Too long a time may damage the normal skin tissue. Choose "cream" for the blister type. The characteristic of blister type tinea pedis is that it is very itchy. Small blisters will appear around the toes at the beginning. Do not scratch or prick the blisters at this time to prevent secondary infection. Use cream for medication selection and avoid using alcohol preparations such as athlete's foot water to avoid causing allergic reactions. Antifungal drugs are recommended for this type of tinea pedis in the early stages. If you suffer from tinea manuum and tinea pedis at the same time, you must treat them together and use antibiotics under the guidance of a doctor, and be careful to ensure a sufficient course of medication. For the erosive type, use "lotion" first. The symptom of erosive tinea pedis is that the skin becomes soaked and white, and then slowly peels off. It will also feel very itchy. It is not recommended to use soaking liquid for this type of tinea pedis. Because once there is a ulcerated wound between the toes, the soaking liquid may make the wound ulcerated worse or even cause bacterial infection. [2] It is also not recommended to use ointment directly, as this will make the feet worse. The correct way is to use lotion and pay attention to protecting the wound surface, avoiding washing with water and using soap. Keep the affected area as dry as possible before using antifungal ointment to prolong the time the drug stays on the body surface. Finally, put on antibacterial and anti-odor socks to inhibit the growth of bacteria on the feet and avoid reinfection.
