Prickly heat is usually self-curing; however, it is not self-curing if it is associated with secondary infections, or if the symptoms are severe, such as pus rash or prickly heat. Prickly heat is mainly caused by the high temperature outside, resulting in poor sweat drainage, causing the appearance of pinpoint blisters on the skin, accompanied by itching and so on. 1. Prickly heat can be cured by itself: If the symptoms are mild, prickly heat will recover by itself after the patient leaves the hot environment and can be cured by itself. 2. Prickly heat cannot be cured on its own: If the symptoms are severe, forming pus prickly heat, deep prickly heat, or secondary bacterial infection, it may not be cured on its own, and the patient needs to go to the hospital in time to take appropriate treatment measures. If prickly heat is not cured by removing the high temperature environment, you need to go to the regular hospital for examination in time and follow the doctor’s instructions.
