Thanks for writing in.
The condition you are suffering from can be folliculitis
You can use Tbact cream cream over the affected area twice daily .
Also you can use a good antibacterial soap like SOAPEX soap for bathing.
Also you can continue augmentin
cource of 5 days it will help a lot.
Use ABZORB powder to prevent recurrent infection.
Few prescription drugs and antibiotics can help a lot in cure of this problem.
Hope this helps.
I encourage you to visit a qualified dermatologist
for confirmation of diagnosis and prescription medicines.
