Sorry to say, I had one about 4 months ago and would not have one again unless my life was in danger!!!! Unlike the previous post from the person who had one in 85 and had to sit up afterward, now they want you to recline for the rest of the day after the procedure. The procedure itself isn't too bad but I might warn you of the possibility of what they call a spinal headache. Its when the hole in the dura does not close and you leak spinal fluid so basically the brain is bouncing around in your skull instead of floating like it should. It is like a severe migraine. Mine started the day after the procedure. I called the radiology group that did the procedure and they said to just take it easy for another day, take tylenol and drink plenty of fluids. Well, after I was on my back for 2 days after that I couldn't take the pain anymore. I could not sit up or stand for more then 5 minutes without my head feeling like it would explode. So I called the doc who had ordered the test. They said that in these cases they can do what is called a blood patch. It's where they draw blood out of your arm and do an epidural and inject the blood into the spine to close the hole. I wasn't thrilled about getting stuck in the back again but I had relief within 5 minutes. I wished I had done it sooner. So if you are one of the few that end up with a spinal headache, and you will know it if you do, ask if you can get a blood patch. The anasthesiologist who did mine said that these headaches can last weeks if not treated. And trust me, you don't want that. Hope your experience is better than mine. Don't mean to scare you. Good luck!!!
