How Can Ear Pain And Pressure With Tinnitus Be Treated?

well, i went swimming today, and ( as always) water gets in my ear, and it hurts when i go to the bottom of the pool. i usually take q tips to try and get water and wax out of my ear. i always end up just making it worse, and push all of it back into my ear. now i feel pain and pressure in my left ear whenever i hiccup (i get them alot). i also cant hear that well, i can hear whats going on in my mouth whenever i chew, its rly loud, and i also hear a white noise, along with my pulse. i would like to know why this is, and how i can fix, and prevent this.
