Why are both sides of the buttocks always itchy?

The itching may be caused by eczema, primarily due to allergic reactions. Exposure to synthetic fiber underwear or irritation from sweat can trigger such allergic responses. In some patients, folliculitis may be the cause; this condition could result from a fungal infection of the hair follicles, leading to localized redness and itching. Therefore, when skin itching occurs, an immediate examination is necessary to confirm the diagnosis. Simple cases of eczema can be treated with Haijun Cream. Folliculitis mainly requires antibacterial and anti-inflammatory medications.
