Even after doing a lot of sets, muscle swelling goes away within a day.
Scientific Claim
Muscle swelling following resistance training returns to baseline within 24 hours, regardless of training volume (7–21 sets per session).
Original Statement
“There were actually no significant differences in responses between the different set numbers, and swelling had more or less fully subsided 24 hours after the workout for all set numbers.”

Don't Sweat the Swelling: Exercise Volume's Transient Effects in Trained Males.
No matter how many sets the guys did—whether 7 or 21—their muscles swelled up right after working out but went back to normal within a day, every time.

Muscle Swelling and Neuromuscular Responses Following Blood Flow Restricted Exercise in Untrained Women
The study found that muscles swelled up right after exercise but went back to normal within a day, no matter how hard the workout was — which matches the claim that swelling goes away in 24 hours.
Contradicting (1)
The study looked at how different arm positions affect bicep swelling after workouts, but it didn’t show that the swelling went away within 24 hours — it just measured it for a few days without saying when it returned to normal.
