okay, I had the spinal tap on the 20th, on the 21st I got the worst headache I have ever had in my entire life. I couldn't sit up for longer than 20 minutes, or my head felt like it was going to explode. I was dizzy, shaking, horrible. I called neurologist on 23rd, he wasn't going to be in until wed 28th, nurse said if headache was that bad go to ER. I toughed it out but on 24th I called my regular doctor and he said give it 24 more hours and then call him back if not any better. I called him the next day and off I went to the ER. The anestheseologist there did a blood patch which took care of the killer headache but now I have a bad back pain because it took a while to get the right spot for the blood patch. When will this be over and I feel normal again?
