Formation Of Lumps On The Skin:
Due to the clogging of sweat ducts under the skin, there is a formation of heat rashes on the surface of the skin. In the case of heat rash, there is a development of tough lumps or cysts on the surface of the skin and feel like large peas appearing from beneath the skin layers. There is also the formation of fluid-filled papules which break easily on itching and even on touching. The fluid-filled blisters or papules are very itchy, too, and cause swelling in the surrounding area too.
