Welcome to HCM.
You have not mentioned about your age. If you are old, do you have Diabetes
In younger age group pimple are common. In the presence of Diabetes recurrence of Staph infection is likely.
So the diabetes must be controlled to the maximum extent possible. If you are on any other types of immuno-suppression therapy like steroids
then also you are prone to get recurrences.
You can have a culture and sensitive test and appropriate antibiotics for an extended period will give you good result. Some of the strains of Staph are resistant to common antibiotics, so culture and sensitivity will be very much beneficial.
Antiseptic soaps, antiseptic bathing will also be helpful and rule out any source of staph from other sites of body like nail bed etc.
You will become alright soon.
Wish you a speedy and total recovery.
