My BF's uncle just had MRSA. He didn't get it in the hospital. He was in Hawaii and tripped, broke his fall with his hand and touched some old lava. Came back to Cali, went to the hospital cuz he too had an in grown hair, or what looked like one, and was told he had MRSA. They're not exactly sure that it came from that, but that's what they think. The locals told him not to touch the stuff.

Sorry you have it, it's a pretty scary thing! Glad you're out of the hospital!
