Hello everyone! I am new here and I and I need your advice/help. For the last couple of weeks I have been having these bad headaches that feel like I am under water and like there is a vice grip on on my. I'm dizzy. I have been having nose bleeds but only one side of my head where the valve is. my shunt replaced 4 years ago . I went and got the CT-scan and my doctor who is notorious for waiting till i am in the ER to start to worry says there is nothing. The other doctor in the room says I might have slit ventricle syndrome is there anything I can do to help the pain? Should I be worried ? Any suggestions on what to do? please help! Thanks
