Hi, I have just joined this site and read your message. As you also live in Victoria, I was hoping for the name of your surgeon or hospital that can help. My close friends have a son that has the same arachnoid cyst as yours, and are desperate to find more help. They are currently in Queensland and although they have tried many and indifferent ways to combat his headaches and pain etc., unfortunately to no avail. They are hoping to find a surgeon that has more knowledge in this area. I hope you can help us. Regards
