I could be wrong but you may have a placebo effect that is hurting your head, not the actual flickering, patrickp.
LCDs do not actually refresh the same way as the CRTs do, "refresh rate" of LCD is actually a response time.
That means how fast will the pixel be changed. It has the same brightness all the time until it's changed.
As for the backlight used to illuminate liquid crystal shutters according to Wikipedia it is usually 200Hz, regardless of response time.
So lower "refresh rate" on LCDs will only lead to ghosting and not flickering.
