Staff-like infection pimple on Legs?

Recently, i have discovered pimple like bumps on my legs. They are about 1 to 2 inches apart and have little pus. When i pop them, they just get bigger and stay. When i went to my doctor, he said they were staff so he gave me bactroban. Now, 2 months later, it is only getting worse. The pimples are there even though i used the cream three times a day. It is even spreading and is there is one on my wrist and another near my vaginal area. Other information is that i am a swimmer and spend 5 hours a day at a pool, it that would affect it in anyway.
What could this be?
Could it have anything to do with aids?
