''At this stage of one's career it is not possible to bring about any major change in the bowling action. A little bit of change here and there can be done. But nothing major,'' Nehra said in Kolkata.
The left arm pacer said that injuries were part and parcel of a pace bowler's life anywhere in the world considering the packed cricket calendar. ''Moreover, fast bowling is a difficult job in Asian conditions.''
Nehra also refused to give much importance to former Australian quick bowler Bruce Reid's observation that he change his 'risky' action which made him prone to injuries.
''Everybody has his own opinion. But each bowler has his own style,'' he said.
Nehra disagreed with a scribe that he had 'more than his share of injuries' contending that during the 2002-03 season he had played continuously for 16 months without injury.
But after a dream run in last year's World Cup, where he picked up a rich haul of wickets, injury blues again haunted Nehra and the bowler had to stay out of competition for several months. In the tri-series in India later the same year, Nehra was dropped after the first game, while in the subsequent Australia tour, he was omitted after hurting his left ankle during a One-dayer.
Nehra found a place in the Indian squad for the historic tour to Pakistan in March-April this year, but split the webbing of his bowling hand in the second One-day International and missed the remaining limited over matches and the first Test
Though he was available for the second Test, Nehra was only considered for the final Test returning figures of two for 60 and one for 20.
Nehra said that pace bowling consultant Kapil Dev, who guided the country's leading speedsters in a five-day fitness camp in Bangalore earlier this month, also did not suggest any changes in his bowling style.
''The main thing for a bowler is to bowl at a good line and length. And Kapil Paji said the same thing,'' he said.
Asked what he was doing to get over the injury problems, Nehra said, ''Injury is not in my head. We can only work hard. And I hope to be completely fit throughout the coming season where we play Tests against teams like Australia and South Africa."
Nehra also disapproved a suggestion that he adopt a pick and choose approach to cut down on the number of matches in order to remain fit. ''I think one should play as long as he is fit.''
Expressing happiness with the guidance he received from Kapil in Bangalore, Nehra said, ''Paji is always a big inspiration. It's always good to spend some days with him.''
He described the camp for fast bowlers and the subsequent conditioning camp in Bangalore as 'good preparation' for next month's Asia Cup. ''I hope next month's preparatory camp in Chennai will also be good.''
