What should you know about moderate cellulitis?

Cellulitis can start through a small cut, cracked skin, insect bite, or another break in the skin. It often affects a leg, arm, or face and may feel hot, tight, or painful. The edge of redness can enlarge as inflammation spreads through tissue beneath the surface. Athlete's foot can create cracks between the toes that allow bacteria to enter, while Type 2 Diabetes may make skin infections harder to control. Fever or feeling generally unwell can accompany the local changes.

Arrange same-day medical advice so a clinician can examine the area and decide whether an antibiotic is needed. Take any prescribed medicine exactly as directed and complete the course unless the prescriber changes it. Rest the affected limb, keep it raised when practical, drink fluids, and wash hands before touching the skin. Do not squeeze, puncture, or massage the area. Marking the outer edge of redness with a pen can help you notice whether it is spreading, but it does not replace assessment. Keep any wound clean and covered as advised.

Seek emergency help if redness is spreading quickly, pain is severe or disproportionate, the skin becomes dusky or blistered, or you develop confusion, faintness, breathing difficulty, a very fast heartbeat, or marked weakness. These can signal a serious infection, including sepsis. Urgent review is also warranted for facial or eye-area swelling, reduced movement, or a high fever. People with Type 2 Diabetes, poor circulation, immune suppression, or a recent operation should seek advice promptly because complications may develop without dramatic skin changes.

Ask which features make the infection moderate, whether a swab or other test is useful, how soon improvement should begin, and what to do if the redness extends beyond the marked edge. Discuss wound care, recurrence prevention, and whether Athlete's Foot or another skin break needs treatment.
