What should you know about uncomplicated cellulitis?

The affected area may become warm, tender, swollen, and red, with the redness sometimes spreading outward. A small cut, blister, insect bite, wound, or cracked skin can give bacteria an entry point. Athlete's foot may create cracks between the toes, while Type 2 Diabetes can make skin infections more concerning. Cellulitis is different from a surface irritation because it involves tissue beneath the outer skin. A clinician may examine the borders, temperature, pain, and general symptoms to decide whether oral treatment is suitable.

Arrange a medical assessment as soon as practical, especially if the redness is enlarging or the area is painful. Keep the skin clean and covered if there is an open area, rest the affected limb when possible, and raise it to help with swelling. Do not squeeze, puncture, or massage the area. If medicine is prescribed, take it exactly as directed and finish the course unless the prescriber changes the plan. Marking the outer edge of redness can help you notice whether it is spreading.

Seek urgent help if redness spreads quickly, pain becomes severe, swelling affects movement, or you develop Fever, chills, confusion, marked weakness, blisters, or skin that turns dusky. Emergency assessment is needed for breathing difficulty, faintness, or signs that the infection may be affecting the whole body. People with diabetes, poor circulation, immune problems, or a recent operation should use a lower threshold for prompt review.

Ask which findings support cellulitis, whether a wound or fungal infection could be the entry point, how soon improvement should begin after treatment, and what change should trigger a return visit. Ask how to protect the area while it heals and whether any medicines or health conditions alter your plan.
