Hi, I have been having issues with this for the past few years. But it currently seems to be getting more common. Everytime I dive into the deep end of the pool, I get a throbbing pain above my right eyebrow. I swam today, and dove. And my eyebrow hurts even more now. Any idea why the water pressure is only affecting my right eyebrow, and nothing else? And also, how can I relieve the pain? Thanks!
