Ear injuries are common for new divers. There's no need to aggressively blow through your nose to clear a mask. You are probably right about your self assessment and blew too hard causing your inner ears to expand too much. Just keep practicing. As for clearing your ears, you should begin right when you splash. If you feel pain it's already too late and you risk injury as you will likely be negative and descending. Clear early and often.
The swim test isn't especially practical during actual diving because you'll have your BC which of course will keep you on the surface reducing the energy needed to swim long distances. IMO, the test is also often rushed to complete the goal and results in fatigue before finishing the distance. There's no time limit, per se. You just need to set a better pace. The treading water test is also often not done correctly, especially in a calm pool. Lots of people will kick like crazy to stay on the surface when in reality most people can simply float on the surface using their lungs to generate positive buoyancy. At the end of the day I would not let those two tests get to you mentally; however, it would be wise to maintain a decent level of physical fitness for diving.
Great advice. AFAIK, the instructor didn't really go over equalizing. I'm familiar with it, though, since I recall various methods from my first Scuba trips in PH. Also, we were a pool that was max of 5ft deep. Perhaps, that's why equalization never came up.
Unless your nose was clogged, my guess is that the ear problem was equalization and the not mask clearing drill itself. It just manifested later, or that's when you noticed it. After all, that is just exhaling through your nose, which you do all the time without causing ear problems. You even sneeze.
Take extra care and work on equalization - early and often. There are lots of tips and tricks and what works well for one person isn't always the best for another, but you'll get there. That's what I'd focus on. I doubt your clearing technique had anything to do with it.
Don't worry about the swimming. It isn't a race. If you feel like you need a little swimming instruction, I'm sure your instructor can point you in the right direction. A little technique and, just as important, finding a pace that doesn't blow you out, will make all the difference.
I'm not sure, I don't really remember specifically attempting to equalize, but I appreciate the info. As mentioned above. I don't think the instructor discussed it, but it may have happened while I was submerged and didn't realize everyone else was above water (I doubt it though). It's still a possibility and the whole equalization thing still confounds me. I do the "pinch your nose and blow gently" and I never feel any pop or have any indication that I've equalized. However, I did this before when Scuba-diving, and despite not having any distintive cues that I had equalized, everything seemed fine.
If you have access to a pool, maybe try swimming on your back as the instructor suggested (once you've seen a doctor about your ears). Go slowly and see if you can do the required distance without exhausting yourself.
I struggled with the OW swim test; I was also the slowest one, and it wore me out. I swam with a freestyle stroke, which I guess I assumed was the way to go, but I know my form sucks and I had trouble getting enough air. I knew this was going to be a problem for the GUE Fundamentals swim test, which is 50% longer and it's timed. But when I talked to some people who had done it, several mentioned doing it in backstroke, so I decided to try that. I easily completed the distance well within the time requirements without getting any fitter. Now I'm trying to arrange some swim lessons to help with the submerged swim portion, since as I like to say, I'm really good at that whole NOT holding my breath thing.
Incidentally, I've also found I greatly prefer doing surface swims on my back rather than using a snorkel. When doing a surface swim in full gear, my posture is more like sitting in a recliner vs. lying flat, and since I have fins I don't need to use my arms, but it's still pretty similar.
This sounds exactly like my problem.. only I SUCK at floating on my back. Like I can try to relax and lay on my back, but my legs/waist always sink like they're made of lead and I end up vertical. Ironically, I can float pretty well if I'm face down. I guess I'll practice trying to kick my legs to help stay afloat, but I feel like my head is centimeters away from going under which causes light panic.
As far as seeing a doctor before I swim again. I don't know if that's possible. I called today for a physical, but they're booked until Nov 22nd. I have to take my next scuba class this upcoming Sunday. Also, I really want to go to the gym and practice these swimming techniques as much as possible before I leave. Is there any health risks involved in swimming before my ears are checked.
ATM, I'm only feeling an occasional "light" feeling of soreness, but for the most part, they feel like they did before the incident.
