Bollywood actor-director Ajay Devgan is suffering from excruciating back pain ever since he shot up 25 feet on a harness for a scene in his forthcoming animated venture "Toonpur Ka Superhero".

"Too much of harness have finally taken a toll on my back and today I write my diary from home'" Ajay posted on his blog.

He narrated how while shooting for the film July 31' he developed the back pain and wrote: "I knew and I was prepared for a particular shot which was planned...this shot wherein I was supposed to get blasted away by this great villian from the toon world.

"I was strapped up and at a push of a button I was going to get pulled back and the pulley was hydraulically powered and the pull took me up about 25 feet in a wink of the eye... and that's that... oouch!"

In the film' Ajay has been paired opposite his wife Kajol.

Since the actor is resting at home' he is feeling distressed by the fact that his "crucial time is lost without any work and a commitment is broken. That is what I dislike'" he said.

He hopes to get back to work soon and is confident that his fitness regime will aid him in doing so.

"I guess I will be back on feet as my workout regime has always helped me in recovering from any such unwanted circumstances'" Ajay concluded.
