I have gotten bad staph infections 3 times, all after cycles. I think it is because your immune system is somewhat comprimised when you are coming off and you system is just out of whack. Staph is a bacteria that lives on your skin, it is possible to get it at anytime. But, my Doctor(an infectious diseases specialist) has told me that it usually attacks when the immune system is weakest. The new stuff our there, called MRSA, is even more aggressive. The shit just takes over you body fast. A buddy of mine got scraped by a client he was trianing and almost lost his arm a few months later. The doctors didn't even realize what it was right away. MRSA sucks! Not trying to scare you, but don't screw around with it. If you think something is wrong, see the doc!
