Playback singer Sonu Nigam has been hospitalised due to low blood pressure, fatigue and minor slip disc.
"Sonu has been advised complete bed rest for the next few days for treatment of low blood pressure, fatigue and minor slip disc. He is also suffering from tennis elbow in both his arms and is currently undergoing treatment for that as well," Sonu's publicist said while declining to disclose the singer's whereabouts.
Sonu, over the last couple of year, has been shuttling between the US and India as well as travelling across the globe for stage shows.
The 36-year-old singer had teamed up with pop singer Kylie Minogue for 'Chiggy Wiggy' number in 'Blue' and ended 2009 with 'Aal Izz Well' and 'Zooby Dooby' in '3 Idiots'.
Sources close to him say that Sonu's main concern and worry now, is his forthcoming set of tours to be held in Singapore and Israel.
"He is doing everything in his power to get back on his feet as soon as possible," the publicist said.
