Can you hurt your ears from scuba diving?

Answer 1

Yes you can.

You must be careful when Scuba diving. as you descend into the water, the pressure increases. you have air in your ears that feel this, and it hurts. they are called squeezes. to stop this, you must equalise the air spaces.

to do this, you could hold your nose, shut your mouth, and breath out.

or swallow, and wiggle your jaw.

Most prefer the holding your nose one, but i personally like the second.

If the squeeze doesn't stop, you must not go down further. do not force it, so ascend a little, and try again. if nothing works, stop the dive.
