Fever with non-itchy, non-painful bumps or blisters all over the body—what could be the cause and what should I do?

Fever refers to an elevated body temperature. The appearance of non-painful, non-itchy bumps or blisters all over the body may be caused by conditions such as infantile exanthem, sebaceous cysts, or thrombocytopenic purpura, among others. Treatment should be based on the specific diagnosis. Details are as follows:

1. Infantile Exanthem

This is usually an acute febrile rash caused by human herpesvirus 6 or human herpesvirus 7, commonly occurring during infancy and initially asymptomatic. Over time, it may progress to symptoms such as decreased appetite, high fever, and mild tonsillar congestion. Medications such as Shiduqing Capsules or Pifuxuedu Pills may be taken under medical guidance.

2. Sebaceous Cyst

This condition is primarily associated with blockage of the hair follicle sebaceous gland duct, which prevents secretions from being expelled normally, leading to raised areas on the skin surface. It may also be accompanied by swelling and pain. Topical treatments such as erythromycin ointment or mupirocin ointment can be applied under a doctor’s direction.

3. Thrombocytopenic Purpura

This may be related to immune system dysfunction or infections. After onset, it may cause swelling and bleeding of the skin and mucous membranes, appearing purplish-red. Treatment may include taking medications such as Shengxuebansuan Capsules (Platelet-Increasing Capsules) under medical supervision.

In addition to the above causes, such symptoms could also result from lipomas, fibromas, hemangiomas, or other conditions. Avoid scratching with hands and maintain cleanliness of the affected area.
