Does anyone ever experienced a crick in their head? I know that sounds crazy but it's like a crick in your neck or a cramp in a muscle but only in your head I have never talked with anyone about it but it's getting so bad in the back of my head it looks like I'm going to have to. I  was diagnosed with cancer in 2008 and I'm just praying it's not nothing like that again. Any feedback would be greatly appreciated!!
