Dont shy away from shunts folks, I got mine in April and it was one of the best things ive done. Within 48 hours my eyesight was perfect again (id lost a lot of peripheral and had intermittent total loss) and after 7 bad days while my head adjusted to its new pressure, another week and I was good as new. I had it adjusted a few weeks later which was pretty horrid for a few days but on a day-to-day basis my iih is almost forgotten.
Id rather have the surgery and a few weeks unpleasant recovery than be continually pumping my body with drugs with a multitude of side-effects.
Obviously we are all different and have different symptoms and requirements so I understand shunts arent for everyone. But I also know how scary they sound beforehand, and what amazing results they can have.
