Hi Betty,
i find the positioning of the shunt a total pain in the neck!!

Sun glasses and Alicebands/headbands also cause me grief, ive also been told i need to wear glasses for vision in my right idea which went up the wall after my last full shunt revision!!

When i wear my Alice band, I do get sharp shooting pains, like a sharp thump to the shunt, near the valve area.
I do get this without wearing one, but it tends to reoccur alot when im wearing glasses or the headband.

I havent queried it with the hospital, as although it was uncomfortable with my last shunt too...i never had the pains, only since this shunt.

Hope youre well
Take care
