Mumbai, Jul 21 (IANS): Bollywood star Salman Khan, who has been battling health issues and even underwent surgery for Trigeminal Neuralgia, a facial nerve disorder, says it is important for actors to forget such problems while shooting as the pain and discomfort can't be reflected on screen.

"In spite of all the nerve problems and the aneurism and the travelling and cold and the pain and all that stuff, eventually it's what you show on screen. You can't put subtitles saying - 'Here the actor was unwell' or 'here was a backache' or 'here the cold' led to pain or 'a headache happened'! You can't say all that," the 46-year-old said here.

"You have to give a shot and forget about all that for those 20 to 30 seconds. It is easy to put aside everything if you are interested in the film you are doing," he added.

Salman, who underwent surgery for a facial nerve disorder last year, was warned against rigorous physical action. But he underwent extensive Parkour training for a month to pull off the daredevil stunts in his forthcoming film "Ek Tha Tiger".

In his over two-decade-long career, Salman has got a lot of nicknames thanks to his films, and he is happy about it.

"I have a lot of names - Bodyguard, Dabangg, Wanted, Most Wanted, Veer and now Tiger. I'll get some other name in the next film," said Salman.

"Ek Tha Tiger" also stars Katrina Kaif and is slated for release Aug 15.
