@brav,
my recommendations are;
If its a one of thing.........I will give you a prescription and assuming that you are above 18 years without allergies to certain drugs...in this case penicillins....and if you are a lady...hoping not pregnanat or brest feeding....
you need Flucloxacillin 500mg capsules .....take one capsule four times a day for seven days......(buy from your pharmacist) and you may apply Fucicort cream on the affected areas(but not a must but if extensive pls consider)
If the condition is extensive and big.....ripe...just visit your nearest healthcare facility and have an I & D done (incision & drainage) to expel the content and remember you must take drugs mentioned above even if an I & D is done to kill the bacteria......s.aureus spp
In the event that the condition has been recurring..please consider having the following medical checks done....;
Blood sugar levels for possible glucose impairement
Autoimune diseases eg HIV & AIDs
