Kollywood actor Dhanush who was hospitalised due to severe fever showed signs of recovery this week. Dhanush was at the hospital for more than a week and was absent even at the reception and marriage functions of his sister-in-law Soundarya Rajanikanth. On Tuesday the actor tweeted that one of the reasons for his quick recovery was Rafael Nadal's US Open victory. 'Nadal's victory is my only medicine', tweeted Dhanush. Dhanush will take a week's bed rest at the hospital and will get back to work immediately after.
