Boils issue

Hi

My age is 35.From last one year I am suffering from boils.It appears in last Jan, Oct
and Dec months, so I can say its repetitive boils.

My skin doctor suggest me CEFTUM 250 for 3 days, after that I got relief
say for 15-20 days. but after that again boils starts coming mostly on
leg,on face,on nose and arms area in small amount.

I don't have this before 2009,can you please suggest me the way to
completely overcome from this ?
