Mumbai, Oct 20 (IANS): Megastar Amitabh Bachchan, who has not been keeping well for last few days, appreciates people's concern towards his health, but says there is nothing to worry as the "work continues".

For the sake of his well-wishers, he informed through his post on his blog that Saturday he shot for an ad and also attended an award ceremony.

"Concern after my health has reached an unjustified proportion, undeservingly. More has been attributed to it than was factually correct," Big B wrote on his blog Saturday.

"I am getting better by the day... But your concern is legitimate, and I do appreciate your fond get wells," he wrote.

On Oct 14, Big B had informed that he was down with fever and a stomach infection, but Oct 17 the 71-year-old had resumed work on "Kaun Banega Crorepati".

"Work continues... So did an ad shoot for a client (on Saturday) and had a surprise visit by Priyanka Chopra who was shooting next door... looking stunning as ever! And when that was over, by 9 drove off to receive a youth encouragement award ceremony by the Society Magazine," he furter wrote in his post.

The megastar was honoured with the award at the Society Young Achievers Awards 2013, organised by Society magazine.
