Bam Margera Hospitalized with Staph Infection from Recent Tattoo

Bam Margera is learning hot tubs and fresh ink don't mix -- he needed a hospital stay to treat a staph infection from his latest tattoo.

The "Jackass" star was hospitalized over the weekend after experiencing pain in the same leg that's home to his new Farsi tatt. Bam's no stranger to pain -- it's kinda been his job for years -- so ya gotta imagine he was really hurting bad.

Bam says he had a staph infection, and sources close to him tell us the leg was likely infected when he went into a hot tub.

As anyone with tattoos likely knows, you're supposed to take it easy after getting inked up ... and hot tubs really sound like a bad idea, especially with leg tatts. Tough lesson here for Bam.
