A shunt may be your best answer. Weight loss also seems to help a great deal, so keep trying. If you are having transient blackouts or blurring of vision, the shunt is important to preserve vision, and will also help with the headaches.
thanks Dr. doreen.. I was afraid of that. I'm actually pretty scared. I've only had my tonsiles out and a tubal so i have not had alot of experience wiht surgary.
