YES. itchy scalp is common. Every time they have operated on me (x6)I have the 'itchys'. Initially I thought it was from the shaving of 1/2 my head, but they haven't always needed to shave, but every time I itch.
That 'suspicion of the shunt' is something I am very familiar with and I think it's a normal reaction. But as time goes by you slowly get used to it. Not everything is shunt related, but by the same accord, don't write everything off as insignificant. I ignored symptoms which, in hindsight, I should have followed up on earlier. Now I look for a progression of symptoms. ie headaches are an everyday thing, but a headache with a neck tightness and a visual distortion getting worse is a sign I need to follow up.

It's good to know what to look out for. I'm even having trouble controlling my blood sugar and I'm wondering why this is happening. No change to diet although I haven't been moving as much as I should. I'm also getting not only daily headaches, but head pain, like my head is in a vise. Also neck pain, stiffness. It comes and goes, not constant. I also feel pain right on the top of my head like it is sensitive to the touch. My next appt with my neurosurgeon is in Sept but I may move that up.

Yesterday I had a weird experience feeling off balance while outside, when I came in I had a feeling of dizziness and nausea and I actually did get sick a little. After that I felt better.

Thanks again for your input.
