[MCU] Why is it that Tony didn't seem to be in as much pain as Professor Hulk and Thanos when [SPOLIER]?

Professor Hulk and Thanos are both arguably some of the most powerful characters in the MCU in terms of raw strength. They were both seen struggling tremendously and even screaming in pain to fight through the pain of simply harnessing the power all 6 stones at once. Why did Tony, a human, seem to take the pain better than them?

Un-fun fact about burn injuries: They often hurt a lot less than you expect, because all your nerve endings get destroyed. Hulk and Thanos are far tougher than a squishy little human in a metal suit; as such, their nerves probably lasted a lot longer before that part of the pain went away.

Add to that the fact that his suit probably pumped him full of painkillers and adrenaline, and even the internal injuries probably didn't hurt all that much.
