recovery after cellulitis

Overview

Cellulitis is a common bacterial skin infection that affects the deeper layers of the skin and the tissue just underneath. It usually starts as a red, swollen, tender area, often on the lower leg, and can spread quickly if not treated. Recovery involves taking antibiotics and taking good care of your skin while it heals.

Yes, cellulitis is fairly common. Anyone can get it, but it is more likely to happen if you have a break in your skin or a health condition that affects your circulation or immune system.

Cellulitis can affect people of any age, but it is more common in adults over 45, people with diabetes, people with a weakened immune system, and those who have swelling in the arms or legs (a condition called lymphoedema).

Symptoms

Common symptoms

• A red, swollen, and tender area on the skin, often on the lower leg.
• The skin feels warm to the touch and may look shiny or tight.
• The area may blister or weep clear fluid.
• You might feel generally unwell, with a fever, chills, or tiredness.

Symptoms in children

• Children usually have the same red, swollen patches on the skin.
• They may also be irritable, cry more than usual, or have a fever.
• Sometimes the infection can appear on the face or around the nappy area.

Symptoms in older adults

• Older adults may have less obvious skin redness, or the infection may spread more quickly.
• A sudden change in behaviour, such as confusion or drowsiness, can be a sign.
• They are more likely to develop a high fever and may need hospital care.

Causes

Main causes

• Bacteria (usually streptococcus or staphylococcus) enter through a break in the skin, like a cut, scrape, insect bite, or surgical wound.
• Skin conditions that cause cracks, such as eczema or athlete's foot, can let bacteria in.
• Very dry or fragile skin that tears easily can also be a gateway for infection.

Risk factors

• Having diabetes or poor blood circulation.
• Having a weakened immune system, for example due to an illness or certain medicines.
• Swelling in the arms or legs (lymphoedema).
• Being overweight.
• Having had cellulitis before.

When to see a doctor

See a doctor urgently if:

• If you notice a red, swollen, painful area that is getting worse or spreading.
• If you have a fever or feel very unwell.
• If you have already started treatment but the redness is not improving after 48 hours.

Book a routine appointment if:

• If you have a skin sore that is not healing or keeps coming back.
• If you have had cellulitis more than once and want to find out why.
• If you want advice on how to care for your skin to prevent cellulitis.

Diagnosis

A doctor will usually be able to tell if you have cellulitis by looking at your skin and asking about your symptoms. They may check your temperature and look for breaks or wounds in the skin.

Tests that may be done

• Usually no tests are needed.
• If the infection is severe, the doctor might take a small swab (like a cotton bud) from the area to find out which bacteria are causing it.
• If the infection has spread, a blood test may be done.

What to expect at your appointment

The doctor may draw a line around the edge of the red area with a pen. This helps you both see whether the infection is spreading or getting better. They will likely prescribe an antibiotic and give you clear instructions on what to do next.

Treatment

The main treatment for cellulitis is antibiotics. You will usually take them by mouth at home. You may also need rest, pain relief, and to keep the affected area raised to reduce swelling. If the infection is severe, or if you cannot take medicines by mouth, you may be treated in hospital with antibiotics given through a drip into your vein.

Self-care at home

• Keep the affected area clean and dry.
• Wash your hands before and after touching the area.
• Raise the affected limb on a pillow or stool when resting to help reduce swelling.
• Take over-the-counter pain relief if you need it — ask your pharmacist which one is safe for you.
• Do not squeeze or burst any blisters.
• Use any prescribed creams or dressings exactly as your doctor or nurse advises.

Medical treatments

Antibiotics are the main treatment for cellulitis. Your doctor will choose an antibiotic that works against the most likely bacteria, taking into account your health history and any allergies. It is very important to take the full course, even if you feel better after a few days. In hospital, you may also receive fluids and stronger antibiotics through a drip, and you will be monitored closely.

When is surgery considered?

Surgery is rarely needed for cellulitis. If there is a pocket of pus (an abscess) under the skin, a doctor or surgeon may need to drain it. If the skin becomes badly damaged and tissue dies (a rare complication), surgery may be needed to remove the dead tissue.

Living with this condition

During recovery, you may feel tired and the affected area may stay swollen and discoloured for a few weeks, even after the infection has cleared. Take it easy, rest as much as you can, and keep the area raised. You should gradually return to your normal activities within a week or two, but full healing of the skin may take several weeks.

Lifestyle tips

• Wear loose clothing and let your skin breathe.
• Moisturise your skin every day to prevent cracks and dryness.
• If you have diabetes, check your feet and legs daily for cuts or sores.
• Maintain a healthy weight to improve circulation.
• Protect your skin with gloves and sturdy shoes when gardening or doing DIY.

Diet and exercise

Eating a balanced diet with plenty of fruit, vegetables, and protein helps your immune system heal. Gentle exercise like walking can improve circulation, but wait until you feel better and do not overdo it. If you have swelling in your limbs, keep them raised when resting and ask your doctor about safe exercises or compression therapy.

Mental health and emotional wellbeing

Having a visible skin infection can be worrying and may affect how you feel about your appearance. It is normal to feel anxious or low while you recover. Remember that most people make a full recovery. If you feel very worried or your mood does not lift, talk to your doctor or a counsellor.

Prevention

You can reduce your chance of getting cellulitis again by looking after your skin. Keep your skin clean and moisturised, treat any dry or cracked areas quickly, and treat fungal infections like athlete's foot. Clean any cuts or grazes with clean water, apply an antiseptic if you have one, and cover with a plaster. If you have diabetes, good blood sugar control helps your skin stay healthy.

Vaccines

There is no specific vaccine for cellulitis. However, if you have a long-term condition, staying up to date with recommended vaccines (for example flu and pneumococcal vaccines) helps protect you from infections that could make cellulitis worse.

Screening programmes

There is no routine screening for cellulitis. But if you have had cellulitis more than once, your doctor may examine your skin, circulation, and possible entry points for bacteria. They may also measure your legs for compression stockings to help reduce swelling and prevent future infections.

Complications

If left untreated

• The infection can spread into the bloodstream, causing a serious condition called sepsis.
• It can form a collection of pus (abscess) that needs draining.
• It can damage the lymphatic system, leading to long-term swelling in the limb.
• It can keep coming back in the same area, causing repeated infections.

Long-term outlook

With prompt antibiotic treatment, almost all cases of cellulitis get better within a week or two. The swelling and skin changes may take longer to fade, but your skin should fully heal. If you follow your doctor's advice and protect your skin going forward, you can greatly lower the chance of it coming back.
