How to tell if it’s a boil
- A painful lump that develops around a hair follicle or in an area with hair growth.
- Redness and swelling around the inflamed area.
- Gradual enlargement of the lump over several days.
- Increasing pain or a throbbing sensation in the affected area.
- Warmth of the skin over the lump.
- The appearance of pus or a pale spot in the centre.
- Tight, tender skin over the affected area.
- Drainage of pus if the boil begins to drain on its own.
When a boil keeps coming back: when should you look for an underlying cause?
If purulent skin infections recur, appear in different locations, or return after treatment, it is important to assess not only the current lesion but also the possible causes of recurrence.
One contributing factor may be recurrent infection with Staphylococcus aureus. In some people, this bacterium may be present on the skin or mucous membranes without causing symptoms but, under certain circumstances, may contribute to recurrent purulent infections. In such cases, a doctor can determine whether additional tests or a different treatment approach are needed.
Recurrent boils may also be associated with conditions that affect healing and susceptibility to infection. For example, in cases of frequent recurrence, a doctor may recommend checking blood glucose levels or refer you for an endocrinology consultation if there are reasons to investigate possible metabolic factors.
The location of the lesions is also important. If painful nodules and purulent lesions repeatedly develop in the armpits, groin, or other skin-fold areas, they may not always be ordinary boils. In such cases, a dermatology consultation may be needed to rule out other skin conditions that can have a similar appearance but require different treatment.
For recurrent episodes, the diagnostic pathway should begin with a consultation with a surgeon to assess the active inflammation. Depending on the findings, the doctor may recommend incision and drainage, wound dressings, laboratory tests, or referral to another specialist to investigate the factors contributing to recurrence.
