Hello. Thanks for writing to us at healthcaremagic
I will keep a possibility of Recurrent Furuncle/Boils but I would like to rule out
Hidradenitis suppurativa(HS).
Furuncle/Boil is bacterial infection of the skin and soft tissue; the infection gaining entry through the hair follicle.
Sweating and rubbing/friction being factors that contribute to
recurrent boils in the axilla.
Shaving in this area can also provide portal to entry of bacteria. It should be avoided.
Hidradenitis Suppurative, on the other hand, is a disease of the apocrine sweat glands bearing sites like perineaum, axilla, areola etc where the inciting factor is follicular occlusion with secondary bacterial colonization.
HS is also associated with scaring from previously healed lesions and sinus tracts. This is quite distinctive of HS
The best way to approach in your case is to start on an empirical oral antibiotic for a week OR 10 days (My choice of oral antibiotic would have been either flucloxacillin OR
Cephalexin OR
Cefadroxil).
An OTC antibacterial cream/ointment e.g 2%
mupirocin can be applied twice daily.
An OTC pain killer e.g ibuprofen once or twice daily would help you deal with the pain.
I would also suggest a blood sugar test to rule out diabetes.
