Megastar Amitabh Bachchan is in pain following a spasm in his lower back.

"A spasm of sudden appearance on the lower back, an injury during the many action sequences we did without care or precaution, keeps appearing every now and then to remind us of film and situation," Amitabh wrote on his blog srbachchan.com.

However, the 70-year-old, who has been suffering from health issues for quite sometime, takes the pain with a pinch of humour.

"How wonderful to have such constant reminders. So, injury has importance of place and time. And at times, circumstance. It keeps us informed that we breathe and feel - that we live a living!

Without it we might just be comatose to an oblivious world. In some quarters, the hapless thought of being in company of 'white bearded divinity'," he added.
