Was This Picture Photoshopped?

Mmmm.... Came across this photo while surfing the net and I began to ask questions in which I got answers such as  'In the 80s when Mallams will come to our place down southwest to display their black magic by using sharp blades on themselves by stimulating 'cutting their bodies' where no trace of blood will be seen', another said "it's not Photoshoped, I've seen them live doing it. some pass the knife through their tommy.
it's the more you look, the less you see. na JAZZZZZZ!!" And many more, what do you guys think? See picture after the flip
