Why is my ear messed up?

I woke up this morning with a medium roar/rumble in my ear that sounds kind of like a truck or a waterfall. It started in the back of my head with both ears, then it progressed to my right ear, then to my left ear, then back again to my right ear. It feels like I have some form of pressure in my ears, it makes me feel slightly dizzy, it sounds like I have a bucket over one of my ears, and there is a rumble that comes and goes. I had tubes as a child, but they where removed when I was 5 or so. I had a history of bad ear infections when I was an infant/toddler. I play guitar, sometimes loudly and visit concerts infrequently. What exactly is wrong and what can I do to fix it temporarily and maybe permanently?
