A ha ha i bet i have a staph infection. How do i know? The boils are back on my arm

They appear under my arms and armpit. I get rid of them by slapping those pimple patches on them which gets rid of the pus and dries them up. I ran out of those long ago so i just slapped a bandaid on it. It grew over the past few days and popped today. Damn i am notorious for getting these
