Going by the tweet of Dhanush, the son-in-law of super star Rajnikanth, he has totally recovered from the respiratory problem and is now taking rest in an apartment in Singapore. The happy news is that he doesn’t need any dialysis or for that matter any serious medication. Fans are happy. His return to Chennai is not yet finalised but the movie ‘Rana’ is on its track with filming of the portions excluding Rajni.
