Recurrent boils and abscesses workup
Recurrent boils are usually staphylococcal carriage or hidradenitis suppurativa rather than immunodeficiency - but the workup that separates these, and spots the rare immune defect, is systematic: swab, examine the pattern, screen bloods, and decolonise properly.

Key facts
The essentials at a glance.
The symptoms to recognise, when to seek help, which specialist to see, and what treatment usually involves.
-
The two commonest answers: Staphylococcus aureus (often PVL-positive strains circulating in households) and hidradenitis suppurativa - which is inflammatory, not infective, and concentrates in armpits and groins
-
Swab lesions and nose: culture, sensitivity and PVL testing guide everything downstream
-
Basic screen: glucose/HbA1c, full blood count, and iron status; HIV testing where risk or pattern suggests
-
Immunology referral triggers: abscesses in internal organs, 'cold' abscesses without inflammation, onset in childhood with other infections, poor wound healing, or accompanying lung disease (think CGD, hyper-IgE)
-
Decolonisation done properly - nasal mupirocin, antiseptic body wash, household treatment together, hot-wash linens - breaks most recurrence cycles
Understanding the condition
What it is and what happens next.
What causes it, how it is diagnosed, and the treatment routes available in the UK.
What it is and how it feels
Skin boils recur for reasons that are usually ecological rather than immunological: a staphylococcal strain (sometimes carrying the PVL toxin that favours abscess formation) establishes residence in a person's nose and skin folds and circulates around a household, reinfecting faster than treatment clears it. Hidradenitis suppurativa - misdiagnosed for years as 'recurrent boils' - is a different disease entirely, an inflammatory condition of flexural skin needing its own pathway. True immunodeficiency sits far behind these, and tends to announce itself with company: abscesses in liver or lymph nodes, eczema and pneumonias, or lesions oddly free of heat and pain.
Diagnosis and treatment routes
A structured pass settles most cases: microbiological mapping of patient and contacts, diabetes and iron screening, examination distinguishing follicular boils from hidradenitis, then a rigorous simultaneous household decolonisation - the step most often done half-heartedly. Immunology testing (neutrophil function for CGD, IgE and genetics for hyper-IgE) is reserved for the red-flag patterns and is definitive when indicated. If your boils keep returning despite antibiotics, the answer is a systematic review rather than another course; private dermatology or immunology appointments are typically available within about two weeks.
Seeing a specialist
Who to see, and how quickly you can be seen.
The specialist for this condition is usually a consultant clinical immunologist or dermatologist. Your GP can refer you on the NHS, or you can arrange a private consultation directly.
A quiet reminder
This guide is for information, not medical advice.
Your GP knows your history and can tell you which parts apply to you. If in doubt, see them - and seek urgent care for any of the emergency symptoms described above.
Frequently asked
Common questions about Recurrent boils and abscesses workup.
Quick, plain-English answers to what people ask us most.
-
What causes recurrent boils and abscesses?
Recurrent boils are usually explained by ongoing staphylococcal bacterial carriage on the skin or in the nose, or by hidradenitis suppurativa, a chronic inflammatory skin condition, rather than by an underlying immune deficiency, though the workup checks for this too.
-
When do recurrent boils suggest an immune problem?
An immune cause becomes more likely when boils are unusually severe, start very young, occur alongside other recurrent infections, or fail to respond to standard treatment - features that prompt blood tests to screen immune function.
-
How are recurrent boils and abscesses investigated?
The workup is systematic: a swab to identify the bacteria involved, examination of the pattern and location of lesions (which helps distinguish simple staph carriage from hidradenitis suppurativa), basic immune screening bloods, and a decolonisation plan.
-
Is hidradenitis suppurativa the same as recurrent boils?
Not quite - hidradenitis suppurativa is a specific chronic inflammatory condition affecting skin folds such as the armpits and groin, causing recurrent painful lumps and abscesses, and it needs a different, longer-term treatment approach than simple staph decolonisation.
-
How is recurrent boil formation treated?
Treatment typically combines a course of decolonisation - antiseptic washes and sometimes nasal antibiotic cream for the whole household - with antibiotics for active infections, and specific treatment for hidradenitis suppurativa if that is the underlying cause.
-
Are recurrent boils dangerous?
Individual boils are usually not dangerous, but recurrent infection can occasionally spread more deeply or, rarely, into the bloodstream, and very frequent recurrence understandably affects quality of life, which is why a proper workup is worthwhile.
-
Recurrent boils vs a single boil - what's the difference?
A single boil is usually a simple, self-limiting skin infection needing no special investigation, whereas recurrence (typically defined as multiple episodes over months) is what prompts a structured search for an underlying driver.
-
When should I see a doctor about recurrent boils?
See your GP if boils keep recurring despite basic hygiene measures, so swabs and decolonisation can be arranged, and ask about referral to a dermatologist or immunologist if the pattern persists. A private specialist can typically be seen within about two weeks.
