Top of head pain; shooting pain up neck to top of head

[cowboybilliards]

When I was about 8, I dived off a high dive at a local pool. I clenched my fists when I entered and my head was violently thrown to the right. Instantly, I felt a severe burning sensation on top of my head and my tongue was stiff as a board. It subsided after about 5 minutes but I had the same problem as I grew up if I turned my head, such as startled to the right, down to my knees I would go. I learned to compensate, spent 22 years USN, rode rodeos, but still have the issue. Not sure what can be done. The last doc stated I was having minimum strokes so I didn't go back after cardio cleared me. It is tending to show up more and more as the years go by. I am 63 now. Maybe something got dislodged back then but not sure. MRI's and other scans show age arthritis and some, to me, deviation of the brain to Spinal cord L1 but not confirmed.
