Petechiae are pinpoint-sized spots caused by minor bleeding under the skin, while purpura represents larger areas of similar discoloration. Psoriasis may lead to raised, red plaques covered with silvery scales, often appearing on the elbows, knees, and scalp.
Red Spot on Body Causes Treatment
Mosquitoes, fleas, and bed bugs are common culprits, and the body's histamine response to their saliva drives the visible reaction. Allergic reactions to fabrics, detergents, or topical products frequently manifest as localized redness, hives, or contact dermatitis.
A spot that rapidly increases in size, is accompanied by severe pain, or presents with systemic symptoms like fever or dizziness requires urgent care. In ambiguous cases, a dermatologist might perform a skin biopsy or blood tests to rule out infections or blood disorders.
