DMX is pulling the plug on several tour dates, and his people say it’s because of an unspecified medical issue.

X was supposed to do a show Tuesday night in Santa Ana, California … but the venue informed ticket holders the show had been cancelled due to a “medical emergency.”
According to TMZ’s sources, his Wednesday show in Los Angeles, as well as a Thursday gig in San Diego will also be postponed. TMZ was told several people in DMX’s inner circle have been concerned about his health this week.

Many fans thought he was a little off the rails during his Brooklyn show last weekend, where the Ruff Ryders reunited. TMZ was told X was indeed drinking heavily that night.

He’s battled substance abuse in the past, and friends fear a relapse.
