The film is currently under production here.
The 49-year-old, who is working tirelessly for Rahul Dholakia-directed "Raees" despite undergoing a knee surgery last month, tweeted: "Feel awful the whole of Raees team fighting against rain & time...my injury hampering Ravi Varma, Rahul & Maneka even more. Damn."
Shah Rukh was advised rest by doctors, but the actor chose to work in pain as the crew had to finish some action scenes before the monsoon arrived.
Stunt director Ravi Varma is looking after the action scenes in the film, which also stars Farhan Akhtar, Nawazuddin Siddiqui and Mahira Khan.
Co-produced by Farhan's Excel Entertainment and Shah Rukh's Red Chillies Entertainment, "Raees" is expected to release on Eid next year.
