I have thus far been unable to get an answer to this question. I underwent Microvascular Decompression in May 15, 2009 to treat Trigeminal Neuralgia. After the surgery I suffered a CSF leak for 10 days (I believe it was caused by the shoving of my head into the "holder" for the post-op CT scan..just a guess though). I recieved a blood patch to treat the leak on May 26, 2009. The Trigeminal shocks have pretty well stopped, however, when I cough, sneeze, jump, run or go on a bumpy car ride it feels like my brain is slamming against my skull. I also get headaches now that feel almost as if my head is a pressure cooker about to explode. I also recently made the mistake of riding an amusing park ride (after much proding from my daughter) and it felt as though my brain was being pushed down because of the G-force. I want to know is this normal. I am worried that I am going to give myself brain damage from something as simple as a sneeze or a cough. Please, please help me. I have a 6 year old counting on me and I start nursing school in 2 weeks. If this is normal and I need to learn to live with it I will, I just want to make sure that there isn't something further wrong "up there". Thank you for your help!!
