I would be pleased to answer your question .
This looks like the Staphylococcal infection
of hair Follicles.
Your history and clinical picture are suggestive of 'Recurrent Folliculitis'. The first step into figuring out how to prevent this is to get your blood sugar level done (both fasting and after a meal). Diabetes
is a common cause of Recurrent Folliculitis.
If the sugar level is high then controlling it will prevent new lesions. Besides this here is what I recommend:
ointment twice a day for 5-7 days whenever the bumps come. If there is no improvement within 3 days of this then you will require a 5 days course of an oral antibiotic like Dicloxacillin
500 mg three times a day.
2. Dial Antibacterial liquid soap for bathing. Continue this even when asymptomatic.
NOTE: Dicloxacilllin and mupirocin will require a prescription so I would recommend discussing my recommendations with your GP/family physician. Bacitracin
is an OTC alternative to Mupirocin cream.
