Hi John,my heart goes out to you. I tremember only too well that 6 month after feeling when I was tired of it all, wished I was like before and was scared that I wouldn't get any better. Improvement seemed at a stand still. I can only tell you that for me now 18 months on and alot of the problems you describe that I relate to have almost disappeared. My head gets cold in the winter and hot in the summer ( I haven't had a shunt etc.) and I had creepy feelings in my head and often still do. Hang on in there be as patient as possible,think positive. Your a survivor John a courageous person who's come a long long way in 6 months. Give it more time. I send you big hugs and lots empathy and loads of luck. Maggie x
