I've been having this problem for about 2 years, what could it be?

Ok so about 2 years ago I started getting really bad headaches every day. By really bad I mean REALLY BAD. Sometimes I would feel a sharp pain at the side or the back of my head and sometimes my head would just hurt for hours. Then I noticed that whenever I jump ( I don't know if it's normal or not) I could feel something move in my head (probably my brain). It felt like a knock from inside my head. And I just kept having these headaches for so long. Advil didn't seem to help get rid of them. Anyways, one day I woke up and I had a strange feeling in my ears. It's as if something is inside them. I can't hear myself swallow anymore but I can hear sound perfectly. It just feels like something is "deafening" inside my ears. Then another day came and my ears felt even "deafer". I don't know what any of what I just said to you could be, but I'm going to the doctor next month to talk about it. Still before I go I would like people's opinions on this. I appreciate any answers I get. Thank you.
