Whoa, davebanninga! I'm sorry I did not notice your post until now! You are an important part of our community, and we wish the very best for you!
I'm just glad that you are in no acute danger right now, and that they were able to determine what caused the bad headaches and why you vomited. At least you have a plan of action. Keep us posted after you meet with your surgeon.
I went to the ER on New Year's Day because I was having trouble breathing and I'm not asthmatic. But a thousand dollars later, they told me all the tests came back fine, and they released me without treatment -- which was good, but also puzzling on why I experienced what I did. I'm sure it had nothing to do with my acoustic neuroma. And the only reason I mention it here is that you are fortunate the hospital was able to determine what had happened, and you have a plan for the future.
I will be looking forward to hearing an update on Tuesday!
Take care, my friend!
