MJ's buttocks were scarred from too many drug injections, testifies doc

Michael Jackson's buttocks were so scarred and abscessed from long-term drug injections that the singer's thickened skin nearly broke the syringe of his physician, according to the Dr. Stuart Finkelstein testimony.

The doctor, who treated Jackson in 1993 during his 'Dangerous' tour, testified that the King of Pop's drug problem dated back to the early '90s, Fox News reported.

In a taped deposition that was played for the court this week, Finkelstein stated that he thinks the late singer was addicted to prescription medications.

He said the scarring he saw on Jackson's buttocks from previous injections was "significant" and "extensive."

The doctor implied that the 'Off the Wall' singer also had a high tolerance for morphine.

In his testimony, Finkelstein also said that he and AEG executive Paul Gongaware had five to 10 conversations in 2009 about working on the late singer's 'This Is It' shows.

Jackson's mum Katherine is suing AEG Live for wrongful death of the late singer, while claiming that the concert promoter negligently hired Dr. Conrad Murray as tour physician and set the stage for her son's fatal 2009 overdose.
