What symptom is primarily associated with Stage 1 pressure sores?

Stage 1 pressure sores, also known as pressure ulcers or bedsores, are characterized primarily by localized redness of the skin that does not blanch when pressed. This redness indicates that the skin is damaged but still intact. In this initial stage, the affected area may feel warm to the touch and may also show signs of swelling or a change in texture. The redness is a response to increased pressure on the skin, which can restrict blood flow and lead to tissue damage if not addressed promptly.

While blistering, skin discoloration beyond redness, and pain can indeed occur in later stages of pressure sores or in conjunction with other skin conditions, the defining symptom of Stage 1 is the non-blanchable redness. This symptom is critical in recognizing and treating pressure sores early, helping to prevent progression to more severe stages that involve deeper tissue damage.
