I had the same issues. I was a college gymnast and crunched my neck and mellon falling off rings. I had regular headaches and sensitivity to light. in fact, I would even go blind in one eye from time to time. Physicians had no idea. After telling a local optomotrist, I was told that it would eventually go away. And over time... it did. Today I have episodes about once a year vs once a month. My neck however... could use some fusion! HA!
you're right, my symptoms started after an incident however and then disappeared after a freaky head message. came back after the popping. i see a legit chiro once a year or so. the symptoms don't bother me if i know i'm not going into paralysis or anything like that. i've lived a luckly athletic life coming out of all this stuff pretty clean, but the magic number of age always wins in the end i guess. thanks for the info.
