Driver master big fat more than 40 years old, more than ten years as a driver, driving skills that is not to say, after all, is an old driver. Old drivers also have troubles. Both sides of the thigh root is always itchy, itching up their own fear, when they are alone, with their hands to scratch hard ah, scratch the bleeding can be dripping. Of course, this has a benefit, driving is not easy to sleepy. Often encounter embarrassing situations, just pull on a woman, thigh root and itchy, scratch it, the back row of female passengers think the driver has a special hobby, do not scratch, really uncomfortable, buttocks and thighs twisting around does not relieve. As a decent driver, this would be very embarrassing. There was no way out, the big fat driver came to the hospital dermatology department and his inner thighs looked like this: What is this disease? This is ringworm, which is caused by dermatophyte infection and manifests itself as a slightly elevated red spot with peeling edges, and some people will have small blisters, which can easily break down into infection secondary to itching and scratching, and repeatedly stimulate the skin to become thick and rough; if left untreated it can involve the groin, perineum, perianal and buttocks, and even the whole body. Those people are prone to get it? Obese people, people who sweat, drivers, people with low resistance and diabetics are susceptible, and people with ringworm and gray nails are prone to develop it. How to treat it? Topical medication is the main treatment, such as azoles, acrylamides, cyproheptadine and amorolfine can be applied, such as econazole, terbinafine, bifenazole, naftifine ketoconazole and cyproheptadine can be used. Serious disease can be oral antifungal drugs such as fluconazole, terbinafine, itraconazole, etc. Terbinafine commonly used amount of 250mg/d, or itraconazole 200mg/d, the course of treatment 1 to 2 weeks. Oral drugs are best applied under the guidance of a doctor. Precautions: 1. Pay attention to personal hygiene, do not share clothes, towels and slippers with others. 2, underwear should be loose, breathable, if local humidity, pay attention to local cleaning, keep breathable, dry. 3.Don’t be sedentary, it’s best to stand and move around every once in a while. 4.Treat ringworm and gray nails promptly. 5.Don’t touch the puppy or cat if it has ringworm. 6.Do not stop the medication immediately after the symptoms have subsided and there is no more redness and itching, and then use the medication topically for 1-2 weeks to avoid a relapse. Is it effective to use dermatoprost? I often encounter some people, embarrassed to come to the hospital, in the pharmacy to buy their own dermatoprost, the more serious the result, so do not use drugs containing hormones, but the application of antifungal drugs. Is it necessarily ringworm that occurs in the groin? Not necessarily! Many skin diseases such as chronic eczema, neurodermatitis, scabies, erysipelas, and pruritus can occur in the groin and inner thighs, but they behave differently, and it is best to treat them with the help of a doctor to avoid misdiagnosis and the use of the wrong medication, which can delay the condition.
