Last year for a college credit, I took a diving course. It was an excellent experience but near the end we were required to ditch our weight belt and then do a fast descent to retrieve it at the bottom of the pool (about 13 feet down). During the descent I forgot to equalize my ears, and, as a result, minutely ruptured my eardrum. After I figured out what happened, I asked other students if they had forgotten to equalize at all. Many had, but no one else damaged their ears.

I have a history of sinus issues (mostly just allergies that ended up being sinus infections), but it wasn’t an issue in the pool until I messed up and didn’t equalize the pressure. This all happened in the last week of class before the dive cert., and as a result, I have never dove past 13 feet.

My question is, if I were to be involved in a combat diving program, assuming I didn’t make a dumb mistake (like not equalizing my ears), would having a simple sinus issue like this preclude me from succeeding? My chances of diving again on my own dime are slim, and I would imagine that in the military, if you were to be in the water diving daily for months, this could put a lot of strain on your ears.

Is it unrealistic to think I could succeed at combat diving based on this information?

Thanks for your time,

Nick, your problem isn’t an uncommon one. Unfortunately, even experienced divers, SCUBA and free diving, can forget to clear their ears during a rapid descent. The good news is, your ears and sinuses should heal fine as long as you avoid the water during the healing, or expose them to forced pressure such as plugging your nose during a sneeze. More importantly, be sure to consult your medical provider; self diagnosis is always bad policy, even for medical professionals.

In relation to your question on military diving, you will find the military takes more time to train/teach than our civilian counterparts. There are many reasons for this, but one of the most important is practicing what to do when things go wrong. Top of the list is to remain calm. In order to ensure this happens, the military relies on one word: rehearsal. This is especially true with combat diving. Regardless of the service you choose, all of them will ingrain in you to remain calm and not to forget the small stuff, like clearing your ears. You’ll be fine.
