hello i was told that holding breath and swallowing is a good way to equilize ive tried it and it seems to work pretty well up to about 10 ft but when i come up ears hurt a little till i swallow again and equlize for surface is this normal is this a legit way to eqilize? i have trouble with holding and blowing out doesnt always work both ears well. but this works every time. just dont want to hurt ears. thanks ps the guy who told me this clams to be a dive instructor, but ive never heard of this method.
