cellulitis aftercare at home

Overview

Cellulitis is a bacterial skin infection that affects the deeper layers of the skin. It causes an area of the skin to become red, swollen, warm, and painful. With proper treatment, it usually clears up without long-term problems.

Yes, cellulitis is a fairly common skin infection. Many people get it at some point in their lives, and it can affect anyone, though some groups are more at risk.

Anyone can get cellulitis, but it is more common in people who have a break in their skin, a weakened immune system, diabetes, or a condition that causes fluid buildup in a limb, such as lymphedema. It also appears more often in older adults.

Symptoms

Common symptoms

• Redness and swelling on an area of the skin
• A feeling of warmth or heat on the affected skin
• Pain or tenderness where the skin is affected
• Fever and generally feeling unwell
• The red area may have an irregular border and can expand over time

Symptoms in children

• Fussiness or drowsiness
• Crying when the affected area is touched
• Red, swollen, or warm patch of skin
• Fever, which may be the first sign

Symptoms in older adults

• Redness may be harder to see on thinner or darker skin, but swelling and warmth are usually present
• Confusion or a sudden change in mental state
• Feeling weak or more tired than usual
• Fever may be present but sometimes is low-grade
• Blisters, bruising, or a shiny appearance on the affected skin

Causes

Main causes

• Bacteria, usually streptococcus or staphylococcus, entering through a break in the skin
• Cuts, scratches, surgical wounds, or burns
• Insect bites or animal bites
• Skin conditions like eczema or athlete’s foot that crack the skin
• Breaks in the skin caused by dry or fragile skin

Risk factors

• Having a weakened immune system, for example due to medication or illness
• Having diabetes, especially if blood sugar is not well-controlled
• Having lymphedema (chronic swelling of a limb)
• Being older or having reduced mobility
• Injecting drugs that break the skin
• Having a previous episode of cellulitis

When to see a doctor

See a doctor urgently if:

• Symptoms are getting worse after 48 hours of treatment
• You develop a fever or feel very unwell
• The area of redness expands quickly
• You have a medical condition that weakens your immune system and you think you have cellulitis

Book a routine appointment if:

• You are prescribed antibiotics and need a follow-up check
• You notice any new symptoms during treatment
• You have a home visit scheduled for a wound review

Diagnosis

A doctor will look at your skin and ask about your symptoms, medical history, and anything that may have caused a break in the skin.

Tests that may be done

• Usually no tests are needed for a classic case
• A blood test may be done if the infection is severe or if you have other medical conditions
• A swab of any fluid or wound may be taken to identify the bacteria
• Sometimes an ultrasound is used to check for an abscess (a pocket of pus)

What to expect at your appointment

The doctor will carefully examine the affected skin, check your temperature and general health, and may press on the area gently to see how far the swelling reaches. They will likely prescribe antibiotics and give advice on how to care for your skin at home.

Treatment

The main treatment for cellulitis is a course of antibiotics. In addition, you will be asked to rest the area, keep it elevated, and monitor it for any worsening. Most people take antibiotics by mouth for five to ten days, but your doctor will tell you exactly what to do.

Self-care at home

• Take all antibiotics exactly as prescribed, even if you feel better before the course finishes
• Rest the affected limb and raise it above the level of your heart to help reduce swelling
• Keep the skin clean but do not scrub, and use a clean, dry dressing if there is an open wound
• Monitor the area for changes in size, color, or pain
• Drink plenty of fluids to help your body fight the infection
• Use over-the-counter pain relief only after checking with your doctor or pharmacist

Medical treatments

Doctors usually prescribe oral antibiotics for cellulitis. If the infection is severe, you may need antibiotics through a drip in a hospital. Your doctor may also recommend paracetamol or ibuprofen for pain and fever, but you should ask them for advice first. Never share antibiotics or use leftover medicine.

When is surgery considered?

In some cases, if an abscess (a collection of pus) forms under the skin, a doctor may need to drain it with a small procedure. This is uncommon and is done to speed up healing and prevent the infection from spreading.

Living with this condition

While your skin heals, keep the area covered and dry. Elevate the area when resting, and avoid tight clothing or jewelry around the affected limb. Follow up with your doctor as advised, and complete the full course of antibiotics even if the skin looks better.

Lifestyle tips

• Wash your hands often and keep your skin clean
• Moisturise dry skin to prevent cracks that let bacteria in
• If you have diabetes, keep your blood sugar under control
• Avoid swimming or soaking the affected area until it has fully healed
• Stop smoking, as it can reduce blood flow and slow healing

Diet and exercise

A balanced diet rich in fruits, vegetables, and protein helps your body fight infection. Gentle activity like walking may be fine, but avoid exercise that strains the affected area until your doctor says it is safe.

Mental health and emotional wellbeing

It is normal to feel anxious or worried while you are recovering from an infection. Remember that cellulitis is treatable, and most people get better without long-term issues. If you feel very stressed or overwhelmed, talk to your doctor or a counselor.

Prevention

You can reduce the chance of getting cellulitis again by taking good care of your skin. Treat any cuts or scrapes promptly by washing them with soap and water and applying a clean dressing. Keep skin moisturized, and protect your skin from insect bites and burns.

Vaccines

Keeping recommended vaccinations up to date, such as the chickenpox vaccine, can prevent some infections that lead to breaks in the skin. Ask your doctor which vaccines are right for you.

Screening programmes

There is no routine screening test for cellulitis, but if you are at high risk, your doctor may recommend regular skin checks to catch any breaks or early signs of infection.

Complications

If left untreated

• The infection can spread deeper and cause an abscess
• Bacteria may enter the bloodstream, leading to a serious condition called sepsis
• Lymphatic system damage can cause long-term swelling (lymphedema)
• In rare cases, the tissue underneath the skin can become damaged, requiring surgery

Long-term outlook

With prompt and proper treatment, most people with cellulitis recover completely. Following your doctor’s advice and completing the full course of antibiotics are the best steps toward a smooth recovery. If you notice any worsening, seek medical help early.
