Yesterday I had a mask on and I was swimming into a capsized sailboat to
retrieve things and I suddenly got an odd pressure in one of my ears
followed by a sharp pain just above my left eye The sailboat is by the shore
in 10 feet of water so I was not swimming deep but I tend to be sensitive to
water pressure so that may be a moot point. After the pain showed up I could
not even put my head two feet under water before the pain became
excruciating. I quit swimming at that time. On dry land the pain continued
to annoy me for the next 4 hours and then became maddening for about 3 more
hours and then slowly started to subside. It was such a weird pain in my
head that I was considering going to the hospital right as it began to
slowly ease off. This morning it is still there but nothing like it was so I
am assuming what ever caused it is on the way out. Someone told me it was
likely a "squeeze". I have no diving experience at all so I am completely
unfamilier with the hidden dangers of diving and any terminology associated
with it. What happened? A wayward bubble in a sinus or water behind my eye?
What is a "squeeze"? My eye was not and has not become bloodshot. As I
stated it has subsided and I am confident that it is going away but aside
from being painful the whole thing has been a bit scary. How dangerous is
something like that? Is there a way to avoid it in the future? Thank you for
your time.
