There are large sweat glands on the inner side of the root of the thigh, and this large sweat gland is prone to sweating, and the inner side of the root of the thigh is prone to dampness when it sweats. At the same time, we all know that the inner thigh root is in an environment that is not easily ventilated and is subject to friction, which can easily cause a number of itchy diseases, the most common of which are mainly eczema and ringworm, as follows: 1. Eczema is found, most of which is symmetrically distributed, and it is often accompanied by vesicles and exudation in the acute phase, resulting in blisters, and eczema itching is intense. If the symptoms of eczema, especially in the acute phase, gradually subside and then turn into the chronic phase, it becomes predominantly mossy and the application of hormonal ointments can relieve the symptoms. 2. If it is ringworm, which is caused by a fungal infection, most ringworm starts from one side and the main manifestation of ringworm when it occurs is erythema and papules. For ringworm, you can use antifungal medications such as ketoconazole and miconazole ointments to apply, and you can also take oral itraconazole for treatment. Note that for antifungal treatment, it is important to adhere to it for more than 2-4 weeks, otherwise improper treatment can easily lead to fungal relapse.
