hi all, i'm new here and a little curious about lasting effects/risks from a concussion i had years ago. at the time we definitely didnt take care of it how we should have (with a hospital trip), and looking back i feel lucky to be alive. however long story short, was riding an atv 2 up and the operator rolled it backwards, myself landing head first on the asphalt. i lost consciousness prior to feeling any pain or myself hitting the road, and was in and out for a solid few hours. i was answering questions without issue during consciousness and eventually the initial effects wore off and i was left with a week and a half long migraine. some lasting effects were the inability to shake my head without bringing on pain/headache, and not being able to move my eyes all the way to one side or the other without pain, as well as to this day spotty short/mid term memory especially with names of say people i work with daily, or other seemingly simple to remember things (it can get a little embarassing).

realizing eventually that this was without a question a severe concussion, it makes me nervous at times trying to enjoy things i know do (or can) potentially put stress on my head, such as roller coasters or riding my motorcycle. ive been on roller coasters with little issue (though ive experienced brownouts on a particular higher g-force ride) and always wear a helmet on the bike, so i guess my question is am i worrying too much about another impact being the last, or re-injuring myself simply riding a coaster, considering the severity of the incident along with no post injury care/diagnosis?

thanks!
