So, I Was Snorkeling In Mexico And Went A Little

So, I was snorkeling in Mexico and went a little too deep and my ears popped while under water. They hurt for about an hr after. My left one hurts a little bit still and my right one feels foggy. Later that night, I took a shower to wash off the salt water and cleaned me ears and my left one had dried blood in it. What to do, what to do...
