What Causes Skin Boils In Underarms?
Recurrent Boils or Hidradenitis suppurativa
Detailed Answer:
Hello and welcome to healthcaremagic
I would keep a possibility of recurrent furuncle/Boil OR Hidradenitis suppurativa(HS). HS is not contagious.
Furuncle/Boil is bacterial infection of the skin and soft tissue whereas Hidradenitis Suppurative 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 scarring from previously healed lesions and sinus tracts. This is quite distinctive of HS
The best way to approach is to start on an empirical oral antibiotic for a week OR 10 days (My choice of oral antibiotic would have been Amoxycillin 500mg in combination with clavulanic acid 125 mg, thrice daily, for a week OR Cephalexin 500ng thrice daily OR Cefadroxil 500mg twice daily, for a week). This would take care of the infection. Some times antibiotics may be required to be continued for a longer duration.
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.
Avoid shaving in that area.
