I have problems with my head. Any time I turn my head to right side something pops in my head. Or when I sleep an wake up sometimes pops again in my head. I don't know if this is at the top of my spine that is located in the head or is something in my head. It sounds like it's somewhere between ears. Could it be possible that this could be from brain tumor that is pressing somewhere in my head? I have a light dizziness too and I'm now on antidepressants for anxiety. Please help me with any information.
