A diver's ears can be hurt during a deep dive due to changes in pressure. As a diver descends, the pressure increases, causing the eardrum to push inward. Failure to equalize the pressure by clearing the ears can lead to barotrauma, causing pain, discomfort, and potentially injury.
That is a Scuba diver flag, meaning "diver down."
There are two types of diver down flags - the diver down flag and the alpha flag. The red diver down flag is used when divers are in the water to alert boats to the possibility of divers near the surface, and the blue alpha flag is flown by a boat whenever the mobility of the vessel is restricted.

Water pressure push against your eardrums, with nothing pushing back. The stretching hurts. You need to learn a diver's trick called pressure equalizing.
