Sensitivity to both light and sound are commonly reported symptoms by folks who have any type of injury to the brain. MS is, or course, a disease that causes injury to the brain. But it is worth noting that these sensitivities can be caused by other means as well. I am very sensitive to sound, myself, and prefer the television to be turned down low.
There are a lot of different medical conditions that list photophobia (light sensitivity) as a symptom of the condition, migraine and lupus are likely at the top of the list but even some medications list it as a possible side effect, it's definitely worth getting the health of your eyes checked out.
The list below is a bit out dated now but it will give you some ideas...
"Conditions Commonly Associated With Photophobia
Retinal disease (e.g., cone dystrophy, retinitis pigmentosa)
Personally i am very light sensitive too, i wear polarised sunglasses practically all year round when outside now, and they can't let sunlight get in through the top when it's really bright or i still experience everything i usually do when not wearing sunnies.
Hope that helps......JJ
I wear dark sunglasses whenever I leave the house - everyday. Bright light *****! Get yourself proper sunglasses. It really does make it easier.
