What should you know about herpes cellulitis?

Herpes often causes grouped blisters or shallow sores, sometimes with burning or tingling before the skin changes. Cellulitis more often causes an expanding area of warmth, redness, swelling, and tenderness without a typical cluster of blisters. Skin redness or painful skin may occur with many conditions, so these descriptions cannot replace an examination.

A break in the skin, an insect bite, athlete's foot, or another skin problem can allow bacteria to enter. Type 2 Diabetes and other health issues may affect how quickly an infection needs review. The two conditions can also occur in the same person, which makes assessment particularly useful.

Contact a clinician promptly if redness is enlarging, the skin is hot and swollen, or pain is increasing. Marking the edge of redness with a pen can help you notice spread while arranging care, but do not delay an assessment to monitor it. Cellulitis is generally treated with prescribed antibacterial medicine; herpes requires a different approach.

Keep any open area clean and covered, elevate a swollen limb when comfortable, and avoid rubbing or squeezing the skin. Do not use leftover antibiotics or share medication.

Seek urgent help for rapidly spreading redness, severe pain, confusion, faintness, breathing difficulty, or fever with marked weakness. These can signal a serious infection, including Sepsis, and should not be managed at home. Same-day advice is also appropriate when the face, hand, or area around an eye is involved.

Ask what features support cellulitis or herpes, whether testing is needed, which treatment to start, and how soon worsening redness or swelling should be reassessed.
