acne with fever

Overview

Acne is a common skin condition that causes spots and pimples. Fever is a raised body temperature usually due to infection. When acne happens together with a fever, it can be a sign that the skin has a serious infection or that a separate illness is causing both symptoms. This article explains when to seek urgent help and how to manage symptoms.

Acne is very common, but acne together with a fever is not common. When it happens, it needs attention because it can indicate a deeper skin infection or another underlying illness.

Acne with fever can affect anyone who has acne, but it is most often seen in teenagers and young adults, especially males with severe inflammatory acne. It can also affect people with weakened immune systems or other medical conditions.

Symptoms

Common symptoms

• Painful, tender red spots or nodules on the face, chest, or back
• Pus-filled pimples or boils
• Fever (temperature around 38°C or 100.4°F or higher)
• Skin that feels warm to the touch around the spots
• General tiredness or feeling unwell
• Swollen or painful lymph nodes near the affected skin

Symptoms in children

• Acne is less common before puberty, but if a child has acne-like spots with fever, it may be a sign of a bacterial skin infection (such as impetigo) or a viral illness like chickenpox.
• Children may also have a high fever and appear more irritable or drowsy.

Symptoms in older adults

• Older adults with acne and fever may have an infected skin sore or a condition called folliculitis rather than typical acne.
• Fever can also be a sign of shingles or cellulitis, which require medical treatment.
• Older adults may have less obvious symptoms, so a fever with any skin change should be checked.

Causes

Main causes

• Deep, inflamed acne lesions become infected with bacteria (usually Staphylococcus or Streptococcus) and cause a skin infection plus fever.
• A rare, severe inflammatory form of acne called acne fulminans, which typically causes fever, joint pain, and crusting sores.
• A separate illness such as a cold, flu, or viral infection that happens to occur at the same time as a usual acne flare.
• Hormonal changes or medications that trigger a severe skin reaction with systemic symptoms.

Risk factors

• Teenage years and young adulthood, when acne is most common
• Male sex — acne fulminans is much more common in males
• Long-term use of certain medications (ask your doctor or pharmacist)
• A weakened immune system due to illness or medication
• A tendency to pick or squeeze acne lesions

When to see a doctor

See a doctor urgently if:

• Any acne with a fever of 38°C (100.4°F) or higher that lasts more than a day
• Rapidly worsening skin pain, redness, or swelling
• Fever with spreading redness that suggests cellulitis
• Acne that is suddenly severe and crusting, especially in a young male

Book a routine appointment if:

• Acne that is not improving with over-the-counter self-care and is causing embarrassment or scarring.
• Recurrent tender nodules that come and go without fever.

Diagnosis

A healthcare provider will ask about your symptoms, take your temperature, and examine your skin closely. They will look for signs of infection, such as redness, warmth, pus, and swelling. They may press on the skin gently to check for tenderness and check your lymph nodes.

Tests that may be done

• A swab of any pus or drainage to identify the bacteria causing the infection
• A blood test to check for high white blood cells or signs of inflammation
• Sometimes a skin biopsy (removing a tiny piece of skin) if the diagnosis is unclear

What to expect at your appointment

You do not need to prepare anything special. The doctor or nurse may ask about your medical history, medications, and whether you have any allergies. If the fever is high or you feel very unwell, they might arrange blood tests or a referral to a dermatologist or infectious disease specialist.

Treatment

Treatment depends on the underlying cause. A mild fever with a cold and usual acne may only need rest and usual skin care. If your healthcare provider finds a bacterial skin infection, they will likely prescribe an antibiotic — either as a cream, ointment, or tablet. For severe inflammatory acne like acne fulminans, a specialist may recommend a combination of an anti-inflammatory medication and an oral retinoid (a vitamin A-derived medicine) to normalise skin cell turnover. Never take leftover antibiotics or use someone else's prescription.

Self-care at home

• Take a fever-reducing medication as directed on the packaging and consult your pharmacist if you are unsure.
• Place a cool, clean, damp cloth on the skin to soothe pain.
• Do not pick, squeeze, or try to burst any spots.
• Cleanse the skin gently twice daily with a mild cleanser and warm water.
• Keep any open sores or drainage covered with a clean, dry dressing.

Medical treatments

Your doctor may prescribe antibiotics to be taken by mouth or applied to the skin. For infected nodules, they may need to drain the pus under sterile conditions. If acne fulminans is suspected, a dermatologist may use a combination of oral corticosteroids (to reduce inflammation) and an oral retinoid. All of these treatments require a proper consultation and monitoring. Follow your healthcare provider's advice and finish the full course of any prescribed medicine.

When is surgery considered?

Surgery is not usually needed for acne with fever. However, a doctor may need to drain an abscess (a pocket of pus) with a small procedure to relieve pressure and speed healing.

Living with this condition

If you have acne, it can affect your confidence, but it is treatable. While your skin heals, be patient. Use a gentle routine, avoid harsh scrubbing, and keep your hands away from your face. If you have a fever, rest and drink plenty of fluids.

Lifestyle tips

• Wash your face twice a day with a mild cleanser and pat dry with a clean towel.
• Shower after exercise to remove sweat and oil.
• Change your pillowcase and bed sheets regularly.
• Avoid heavy, greasy cosmetics and sunscreens that block pores.
• If you use any topical acne treatments, apply them to clean, dry skin as directed.

Diet and exercise

There is no strong evidence that chocolate, greasy food, or sugary drinks cause acne. Eating a balanced diet with plenty of fruits and vegetables supports overall health and immunity. Daily exercise helps with stress, but shower afterwards to avoid sweat building up on your skin.

Mental health and emotional wellbeing

Acne can cause embarrassment, anxiety, and low mood. A fever adds to feeling unwell. It is normal to feel frustrated. Talk to your healthcare provider about how it is affecting you — they can help, and support groups exist for people with skin conditions.

Prevention

You cannot always prevent acne flares, but you can reduce risk of infection by not squeezing spots and by keeping your skin clean and moisturised. Treating acne early with over-the-counter or prescribed products can also prevent severe flares.

Vaccines

There is no vaccine for acne. However, staying up to date with vaccines like flu or tetanus is important, because a fever in these circumstances is often from a different infection.

Screening programmes

There is no routine screening for acne. If you have sudden severe acne and fever, see a doctor promptly.

Complications

If left untreated

• A localised skin infection can spread to deeper tissue, causing cellulitis or an abscess.
• Rarely, severe infection can enter the bloodstream, which is a medical emergency (sepsis).
• Severe inflammatory acne can heal with permanent scars and dark marks.
• Acne fulminans can cause joint pain, bone lesions, and severe crusting that requires hospital care.

Long-term outlook

With prompt medical care, the infection can usually be cleared and fever settles within a few days to a week. Severe forms of acne are treatable, but may need a specialist and longer course of therapy. Most people recover without serious complications if they get help early. Dermatologists have many effective ways to help your skin heal and prevent future scarring.
