Cyst: The pea-sized bump is probably a hair follicle cyst called an epidermal or pilar cyst. The redness or heat rash worries me in that the cyst ruptured and the skin around it is now getting infected. You may need to see a dermatologsit and have the cyst removed and then take a 10 day course of oral antibiotics
