What should you know about hemorrhagic cellulitis?

Cellulitis develops when bacteria enter through a break in the skin and spread into deeper skin tissues. In a hemorrhagic form, small blood vessels may leak, creating bruised, purple, or blood-filled areas alongside redness and swelling. The affected skin can feel hot, tender, tight, or increasingly painful. It may occur on a leg, arm, face, or another area, and the visible bleeding does not by itself show how deep the infection is.

A fungal infection such as Athlete's Foot can crack skin between the toes and provide an entry point for bacteria. Diabetes can make skin infections harder to manage, while a spreading infection can sometimes progress to sepsis. A clinician needs to examine the skin and your general condition rather than relying on colour alone.

Arrange urgent medical evaluation, particularly if the redness, swelling, warmth, or pain is expanding. Keep the area clean and gently covered if the skin has opened. Do not squeeze blisters, pierce blood-filled areas, massage the skin, or apply leftover antibiotics or steroid creams. Note when the changes began, how quickly they are spreading, and any fever or chills, and take a list of medicines and medical conditions to the appointment.

Seek emergency help for confusion, faintness, severe weakness, trouble breathing, a very fast heartbeat, rapidly worsening pain, skin turning dusky or black, or redness spreading quickly. Fever with a deteriorating skin infection also needs immediate attention. These signs can indicate that the infection is affecting the whole body or that deeper tissue is involved. Do not wait for a rash to become extensive before seeking care.

Ask what may have allowed bacteria to enter, whether the skin needs a swab or other test, which treatment is appropriate, and how soon improvement should be checked. Ask how to protect a wound, whether an underlying foot problem or diabetes needs attention, and which changes should send you back urgently.
