Big BNEW DELHI - Bollywood megastar Amitabh Bachchan is on bed rest following a stomach ache, but he is more concerned about the health of his politician friend Amar Singh, thespian Dilip Kumar and Shiv Sena supremo Bal Thackeray and keeping himself updated on them.

The megastar went to Lilavati Hospital Wednesday morning after a stomach ache complaint.

I was to travel to Singapore today (Thursday) to be with my dearest friend and family member, Amar Singh ji who undergoes a surgery for a kidney transplant. In this hour of trial, I needed to be with him but the doctors advise a few days of rest and observation for me, he posted on his blog www.bigb.bigadda.com.

Jaya (wife) and Abhishek (son) and Aishwarya (daughter-in-law) are there already and I shall join them soon, health permitting, added Big B who is resting at his residence Prateeksha in Mumbai.

The 67-year-old further expressed concern for Dilip Kumar, who was recently down with malaria and admitted to Lilavati Hospital. He is also worried about Bal Thackeray, who has undergone an angioplasty.

My idol and, I am certain, the idol of millions, respected Dilip Kumar has been unwell and in hospital. I had been in constant touch with (his wife) Saira ji when I was out of the country. I’m now happy to read that he is back home. May he enjoy good health ever, he wrote.

Bala Saheb Thakeray has also been rather unwell and within a short span of time has been in hospital almost every other month. On all those occasions, I have been out of the country and unable to express my concern to him personally. I have been speaking to his son Udhav and he informs me today after I called that Bala Saheb is showing signs of improvement. I wish him good health, he further wrote.

The megastar also recalled Thackeray’s gesture during his 1982 accident.

I shall never forget his concern for my health when I was down in 1982 in the Breach Candy Hospital after the ‘Coolie’ incident. Being a great cartoonist, apart from his political presence in Maharashtra and India, he had most interestingly done a painting which depicted that even though Yamraj (the God of death) had come to visit me, I had been able to fight him off successfully.

“I am not a cartoonist, nor a painter, but I wish similar sentiment to him. May he ever fight off the evil of Yamraj, he explained.

The actor, who was last seen in dud Delhi-6, also wrote that he is still unwell and hasn’t recovered from the stomach ache.

I write in some pain and some concern. I write in the anguish of these repeated episodes in my life… The tests have been conducted and more results followed today. They do not show anything alarming, but the symptoms persist, albeit on a lesser scale than last time, he posted.
