What should you know about cellulitis complications?

Untreated or worsening cellulitis can extend through nearby tissue. Pus may collect and form an abscess that needs a procedure rather than antibiotics alone. Infection can involve lymph vessels, muscles, joints, or bone, depending on its location and depth. In some cases bacteria enter the bloodstream and trigger Sepsis, a medical emergency that can affect several organs. Repeated episodes may damage lymph drainage and leave ongoing swelling.

Complications are not diagnosed from a photograph alone. Risk can be higher when circulation is poor, sensation is reduced, wounds are extensive, or Type 2 Diabetes affects healing. Athlete's Foot and cracked skin between the toes can provide an entry point, so treating those problems may help protect the skin.

Have suspected cellulitis assessed promptly and follow the treatment plan closely. Keep wounds clean and covered, check feet and legs for unnoticed breaks, and avoid picking, shaving over, or squeezing inflamed skin. Elevation may ease swelling in an arm or leg. Tell the clinician if redness continues to spread, pain increases, a lump becomes soft or fluctuant, or you feel less well despite treatment. Do not wait for a complication to become obvious.

Seek emergency help for confusion, fainting, severe weakness, breathing difficulty, cold or clammy skin, rapidly worsening pain, purple or black discoloration, or a sudden feeling of being seriously ill. Urgent review is also needed for red streaks, a new pus-filled swelling, loss of movement or sensation, or cellulitis around the eye. Fever with shaking chills is a reason to seek rapid medical advice.

Ask whether there is an abscess, how deep the infection appears, what improvement should be expected, and whether a wound, foot fungus, circulation issue, or diabetes needs attention. Confirm exactly which changes require emergency care.
