Harmison has struggled for consistency with England in 2007
Steve Harmison is a doubt for England's first Test against India next week after aggravating a hernia problem.
Harmison bowled only five overs on Thursday for Durham against Sussex and will play no further part in the game.
The 28-year-old was due to have surgery next month after being diagnosed during the final-Test victory over West Indies but may now need to bring it forward.
England name their squad for Lord's on Sunday and their medical team will now examine the tall paceman's fitness.
Harmison, who endured a torrid time in the Ashes last winter, also struggled for consistency in the Test series against the Windies, although he has been successful in county cricket this season.

He was hoping to play in all three Tests against India and Durham's Friends Provident Trophy final clash with Hampshire at Lord's on 18 August.
"It's too early to say whether he will play at Lord's," said Durham director of cricket Geoff Cook. "He may have to have the operation earlier than scheduled."
The other concern for England is opener Andrew Strauss, who has been out-of-sorts in all forms of cricket after experiencing a tough time in Australia.
His 77 in the first innings in the fourth Windies Test was only his second half century in 17 Test innings.
The Middlesex left-hander lasted just 17 balls against India as captain of England Lions at Chelmsford on Thursday.
Strauss was again out-of-sorts against the Indian tourists
Strauss was overlooked for the one-day series against the West Indies and omitted from England's 30-man provisional Twenty20 World Cup squad.
"You want to play as much cricket for England as possible, so from that point of view it is disappointing not playing - especially having been part of it for the last three years or so," the 30-year-old said.
"But, if I look at it objectively, I think my strengths are in the longer form of the game. That's when I'm at my best.
"I've got three Tests to show what I can do and to really finish the summer on a high.
"I'm excited about those three Test matches - and at the same time, I recognise that it's important to put behind you what's gone on over the winter and the first part of the summer and really nail home a bit of form."
