The cause of herpes sweat is not yet clear, and it is considered to be caused by a variety of factors, such as heredity, local allergies, dermatophyte infections, mental factors and ultraviolet radiation. In severe cases, multiple small blisters may merge into one large blister, and the patient may experience severe itching and pain. In addition, patients with severe herpes perspiration may also experience erosion, oozing, and cracking of the skin. Patients with sweating herpes should go to the hospital in time, under the guidance of the doctor to take regular treatment measures.
