cellulitis exercise guidance

Overview

Cellulitis is a common skin infection caused by bacteria. It affects the deeper layers of the skin and the tissue just below it. The infected area becomes red, swollen, warm, and painful. It most often appears on the lower legs, but it can happen anywhere on the body.

Yes, cellulitis is fairly common. Many people see a doctor for it each year, and most cases are treated successfully.

Anyone can get cellulitis, but it is more common in adults, people with diabetes, people with poor circulation, and people with a weakened immune system.

Symptoms

Common symptoms

• A red, swollen area of skin that feels hot and tender
• Pain or soreness in the affected area
• Fever, chills, or feeling generally unwell
• The skin may look tight, shiny, or dimpled like an orange peel
• A red streak spreading from the infected area

Symptoms in children

• Children may be more irritable than usual
• They might complain of pain in one area or refuse to use an arm or leg
• A fever is common

Symptoms in older adults

• Older adults may feel confused or unusually sleepy
• They might not have a fever even when the infection is serious
• A fall or sudden change in behaviour can sometimes be the first sign

Causes

Main causes

• Bacteria get into the skin through a cut, scrape, burn, insect bite, ulcer, or cracked skin
• Sometimes there is no visible break in the skin, especially in people with swelling in the legs

Risk factors

• Diabetes
• Poor blood circulation in the legs
• Swelling (lymphoedema) from surgery, injury, or an infection
• Athlete's foot (fungal infection between the toes)
• Eczema or dry cracked skin
• A weakened immune system
• Recent surgery or a skin condition that causes breaks in the skin

When to see a doctor

See a doctor urgently if:

• If you have red, swollen, painful skin, especially with a fever or chills, seek medical care the same day
• If you have a condition like diabetes or a weakened immune system, call your doctor as soon as symptoms start

Book a routine appointment if:

• If you get cellulitis more than once, make a routine appointment to talk about prevention
• If the infection has cleared but you are unsure how to care for your skin, ask your doctor or nurse for a review

Diagnosis

Your doctor will look at the affected skin and ask about your symptoms, any recent injuries, and your general health. They may mark the edge of the redness with a pen to check whether it spreads.

Tests that may be done

• A physical examination of the skin
• Blood tests to check for signs of infection
• A swab of the area if there is an open wound
• Sometimes an ultrasound or other imaging to see how deep the infection goes

What to expect at your appointment

Your doctor will usually start treatment right away. They will tell you to rest and keep the affected limb raised. You may be given a prescription for antibiotics to take at home, and you will be asked to watch the area for improvement.

Treatment

The main treatment for cellulitis is antibiotic medicine prescribed by your doctor. You usually take it by mouth at home. Rest and raising the affected limb are also important to help reduce swelling and speed up recovery.

Self-care at home

• Rest the affected area and keep it elevated on pillows when you can
• Drink plenty of fluids to stay well hydrated
• Follow your doctor's advice about cleaning and covering the skin
• Avoid hot baths, saunas, or strenuous exercise on the infected area until it has healed
• Take the full course of antibiotics exactly as prescribed, even if you feel better

Medical treatments

Doctors usually prescribe antibiotic tablets or liquid for cellulitis. For more severe infections, you may need to go to hospital to receive antibiotics through a drip. The length of treatment depends on how well you respond. Always finish the entire course your doctor recommends.

When is surgery considered?

Surgery is rarely needed, but occasionally a pocket of pus (an abscess) may need to be drained by a doctor.

Living with this condition

While you have cellulitis, plan to take it easy. Keep the affected limb elevated whenever you are sitting or lying down. A short walk to the bathroom is fine, but avoid long periods of standing or vigorous activity. Once the infection is under control, slowly increase your movement as your symptoms improve.

Lifestyle tips

• Keep your skin clean, dry, and moisturized to prevent cracks
• Wear comfortable shoes and socks that do not rub
• Treat athlete's foot promptly
• If you have swelling in your legs, talk to your doctor about compression stockings or other ways to manage it
• If you smoke, try to stop – smoking slows healing and increases infection risk

Diet and exercise

During recovery, gentle movement like a short walk is usually okay if it does not hurt or worsen the swelling. Heavy lifting, running, or intense workouts should wait until the infection has cleared and your doctor gives you the go-ahead. After your treatment is complete, you can gradually return to your usual exercise routine. Stretch and warm up to avoid skin injuries.

Mental health and emotional wellbeing

It is normal to feel worried or frustrated while you recover from cellulitis. If you feel anxious or low, talk to family and friends. You can also mention your feelings to your doctor or nurse – they can suggest ways to support you.

Prevention

You can lower your risk of cellulitis by taking good care of your skin, cleaning cuts and scrapes right away, and managing conditions like diabetes or skin swelling. If you get repeated infections, talk to your doctor about a prevention plan.

Vaccines

There is no vaccine specifically for cellulitis, but keeping your routine vaccinations up to date helps prevent other infections that could lead to breaks in the skin.

Screening programmes

There is no routine screening for cellulitis. The best approach is regular skin checks and prompt attention to any wounds or changes in your skin.

Complications

If left untreated

• The infection can spread into deeper tissues, muscles, or bones
• An abscess (collection of pus) may form and need draining
• Bacteria can enter the bloodstream and cause sepsis, a life-threatening reaction

Long-term outlook

With quick and proper treatment, most people recover from cellulitis without lasting problems. It may take a few weeks for the skin to fully return to normal. Following your treatment plan and giving your body time to heal gives you the best chance of a full recovery.
