It happens to me too, quite often, not all the time. I would love some help to get over this and the underlying problem of not getting past 15M deep.
My conditions/symptoms are:
- no mask squeeze
- I use a very light nose squeeze to equalize, and do it almost all the way down, wiggling jaw etc
- I dive in cold, clean ocean water, 12 deg C.
- I DON'T use fressnel, 'cause I don't know how, yet, have downloaded instructions, just need 6 months dry practice

- I know that my equalization works, because at just less than 15M i feel no pain at all, and, on the way back up, i can feel/hear my ears de-equalize
- i never have nosebleeds otherwise
- I don't have a cold, sinus problems, or use any drugs (a glass of beer does not count right???)
- am 39 years old, and pretty fit/athletic
- rather than a bloody nose, I would say that its more like "rose colored snot" (yuk, sorry)
- I get ear pain at 15M, that I can't equalize away (tried everything, wiggling, re-inverting, going down real slow with deliberate stops) so I keep above that depth, but sometimes hit it "by mistake"
I guess my worries are:
A. am I doing any permanent damage?
B. How will I get over this problem?
C. How will I get past 15M when I have easily enough air (I feel, for double that).
Thanks for the tips if they come..
