Nothing, that's the weird thing. Just started having these weird pain attacks, numbness, tingling. Turns out I have 3 fucked discs in my neck.
I had a consult with a doc who was supposed to be "the man" in cervical spine in Chicago back then. He walked in and said "how long did you play football for?" I told him i never did. He said that a cervical like that could only result from trauma. I told him I didn't have any. He said I was either lying or just didn't remember.
Recently I remembered something. I was 17-18, in Australia. I had learned how and become adept at body surfing. I was on a beach with a strong riptide. the waves would slam because the undercurrent was so strong. I caught one bigger than I probably should have and it slammed me, head first, into the sand.
Other than that, a car wreck at 16, but the doc said no that wasn't it, had to be more traumatic.
no idea.
