trek78 over a year ago. I also get this weird pain in my head. It always is worse in the morning and I frequently wake up with this stabbing pain on the left side of my head towards the top. Also it is near my left ear and it feels like a sharp knife like pain like something is pushing out. Also I get a pulse like feeling where I can feel this pronounced pulse from my heart in this area. It's very weird, and I have looked up all the symptoms for brain tumors, and of course it does sound like that also.
