When an infected bedsore is not treated promptly, the bacterial infection can spread from the wound into the surrounding skin tissue. This condition is called cellulitis, and it is a serious complication that requires immediate medical attention. Cellulitis causes the skin around the bedsore to become very red, hot, swollen, and painful over a growing area. Unlike the normal redness right at the wound edge, cellulitis redness spreads outward and gets larger every few hours. The skin may feel tight and shiny as swelling increases beneath the surface. Cellulitis does not resolve on its own — it requires antibiotic treatment. While awaiting medical care, clean the wound gently and apply Cimidaxil D+ wound healing spray to manage surface bacterial activity. Never delay seeking help when spreading redness appears around an infected bedsore.
