Okay so for pretty much my whole life I've had this very unexplainable pain that would randomly appear in either my head, chest, or throat, or sometimes all those places. However I never get a pain anywhere else without the head pain. 

well recently they're becoming more frequent. The pain is not like one I've ever felt in any other part of my body. 

It's not unbearably painful. It's not really that painful at all, just irritating. It's kinda like a mix between pressure, and hollowness. 

Its starting to freak me out a little given the location of the sensations. 

So if anyone could help or at least say they understand what I'm talking about, it would be extremely relieving.
