The Appearance Of Pus-Filled Bumps:
In a certain type of heat rash, which is in the condition of Miliaria pustulosa, there is the development of white or yellow bumps on the surface of the skin having heat rash. The tiny red bumps of the skin start filling with pus in them and then ultimately turn into white or yellow-colored bumps on the surface of the skin. These fluid-containing bumps or blisters are not that common type of heat rash as compared with the occurrence of other types of heat rashes. The pus-filled vesicles or bumps affect the skin layers deeply and might spread from one area to another due to the contact with other areas of skin.
