My MRI and MR Myelogram turned out okay as well, but a blind blood patch FIXED the same head pressure you describe, so I did have a CSF leak. I would see if I could get a blind blood patch if I were you. My symptoms were just like yours except laying flat did alleviate the pain. I know with time, the positional aspect can go away with a CSF leak. Also- 20% of people’s imaging will come up negative even when they do have a leak. Leaks are elusive.
