Perhaps it's because I have had so many spinal procedures, I don't think this is a real big deal. Yes, it is uncomfortable but it doesn't take long. As for a spinal leak, while they are rare, they are extremely painful. I can't speak from experience but I understand they are worse than a killer migraine. After all of these years and all of the spinal tests and procedures, I did have a spinal leak after my last pre-op myelogram. It was unlike anything I have ever experienced but responded to the blood patch quickly. I guess it was just my turn. Hang in there and try not to let this make you anxious. Best wishes.
