It hurt, and it hurt a lot.
Lee guessed that his first impulse might be to vomit the spark out, or even try to cut it from his chest directly from how much pain he might find himself in. That is why he didn't bring along anything that he could hurt himself with. And now he regretted that.
The moment he swallowed the spark, scorching pain paralyzed him, and he convulsed on the floor in agony, feeling how he was getting burnt alive. Lee felt every cell in his body burning and the worst part was that there was no going back.
Before attempting this ridiculous plan, his idea was that he could use the elemental particles of the earth spark to mostly neutralize the effect of fire, kind of subjugate it, but the water spark would heal him up, soothing the potential pain.
Turns out he couldn't do shit. Not only he couldn't concentrate because of the scorching agony, he felt he barely maintained bits of sanity. And the worst of all was that he couldn't pass out no matter how hard he tried.
