cellulitis at night

Overview

Cellulitis is a common bacterial skin infection. It affects the deeper layers of the skin and the tissue just below it. The skin becomes red, swollen, warm, and painful. At night, symptoms may feel worse because you are resting and more aware of your body.

Yes, cellulitis is quite common. Many people get it at some point in their lives.

Anyone can get cellulitis, but people with cuts, bites, eczema, diabetes, poor circulation, or a weakened immune system are at higher risk. It is also more common in older adults and people with swelling in the arms or legs.

Symptoms

Common symptoms

• A red, swollen area of skin that feels tender or painful
• The skin feels warm or hot to the touch
• The redness may spread over hours or days
• Pain can be worse at night when you are lying still
• Fever, chills, or feeling generally unwell

Symptoms in children

• The affected area might be on the face, arm, leg, or near the navel
• Children may be fussy, sleepy, or less hungry than usual
• Fever is common
• Redness can spread quickly, so check often

Symptoms in older adults

• Redness and swelling may be less obvious, so look for warmth and tenderness
• Confusion or a sudden change in behaviour can be a sign of severe infection
• Skin may blister or bruise
• They may need hospital care more often

Causes

Main causes

• Bacteria (usually strep or staph) enter through a break in the skin
• Cuts, scrapes, insect bites, surgical wounds, or cracked skin
• Skin conditions like eczema or athlete's foot that create openings
• Existing swelling in the arm or leg which makes skin easier to infect

Risk factors

• A recent cut, scratch, or burn
• Insect bite or animal bite
• Dry, cracked skin or eczema
• Athlete's foot or fungal nail infection
• Diabetes, especially if blood sugar is high
• Poor blood circulation or lymphedema
• A weakened immune system from illness or medication
• Previous bouts of cellulitis

When to see a doctor

See a doctor urgently if:

• If you have a red, swollen, painful area of skin and a fever
• If the redness is spreading quickly
• If you feel very unwell or confused
• If you have diabetes or a weak immune system and suspect cellulitis

Book a routine appointment if:

• If you notice new redness, warmth, swelling, or pain, especially after a cut or bite, make an appointment the same day
• If an area of skin is not healing after a few days

Diagnosis

A doctor will look at the affected skin and ask about your symptoms, how it started, and any health conditions you have. They may also feel the area to check for warmth and tenderness.

Tests that may be done

• Usually no test is needed
• Your doctor may take a sample from the skin or wound if there is an open sore
• A blood test may be done if the infection looks serious
• Ultrasound may be used if there is a possible abscess or deeper infection

What to expect at your appointment

The doctor will likely explain the diagnosis, mark the edge of the redness with a pen, and prescribe a course of oral antibiotics. They may ask you to take a photo or note the time so you can tell if the redness is spreading.

Treatment

Cellulitis is treated with antibiotics. You will usually take them by mouth at home. Rest and keeping the affected area raised are also important. Finish the full course of antibiotics, even if you start feeling better.

Self-care at home

• Rest the affected limb and keep it raised on pillows to reduce swelling
• Keep the skin clean and dry
• Mark the edge of the redness with a pen daily to check if it spreads
• Apply a clean, cool, damp cloth to the area if it feels soothing
• Drink plenty of fluids
• Ask your pharmacist which pain relief is safe for you

Medical treatments

The standard treatment is antibiotics taken by mouth. For more severe infections, or if you cannot take medicine by mouth, you may need antibiotics through a drip in the hospital. Your doctor will decide the right approach based on your symptoms and health history. Do not use antibiotic creams alone, because they do not reach the deeper layers of skin.

When is surgery considered?

In rare cases, surgery may be needed to drain an abscess (a pocket of pus) or remove dead tissue. Your doctor will explain this if it becomes necessary.

Living with this condition

During treatment, rest as much as you can. At night, prop the affected limb on pillows to ease swelling and pain. Keep the skin uncovered or lightly covered so you can check it. Take your antibiotics at the same times each day and finish the full course.

Lifestyle tips

• Do not scratch or pick at the affected area
• Cover any wounds with clean dressings and change them as directed
• Treat fungal infections like athlete's foot promptly
• If you have diabetes, keep your blood sugar within your target range
• Avoid swimming or soaking the area until it is healed

Diet and exercise

Eat a balanced diet with enough protein and vitamins to help your body heal. Once the infection begins to improve, gentle movement like walking can help circulation, but avoid strenuous exercise of the affected area until your doctor says it is safe.

Mental health and emotional wellbeing

It is normal to feel worried, frustrated, or low when you have a painful skin infection. Nighttime discomfort can disturb sleep and affect your mood. Be kind to yourself and talk to your doctor if you feel overwhelmed.

Prevention

You can reduce your risk by caring for your skin, cleaning cuts and scrapes right away, covering wounds with a clean dressing, and managing underlying conditions like diabetes or swelling in the limbs.

Vaccines

There is no vaccine specifically for cellulitis, but keeping your tetanus vaccination up to date helps prevent infections from dirty wounds.

Screening programmes

If you get cellulitis often, your doctor may look for underlying causes such as poor circulation, lymphedema, or a fungal skin infection.

Complications

If left untreated

• The infection can spread deeper into the skin and tissue
• An abscess (pocket of pus) may form and need draining
• Bacteria can get into the bloodstream and cause sepsis, which is life-threatening
• Permanent swelling or damage to the affected limb can occur

Long-term outlook

With prompt medical care, most people with cellulitis recover fully within a week or two. Following your treatment plan and watching for signs of spreading infection gives you the best chance of a smooth recovery.
