I was fine at time of injury no symptoms just motion sickness from ambulance which I get all the time. 4 hours later dizzy nausea dry heave. Ct scan nothing sent home labeled as concussion in ER. That night didn't sleep well I'm still only sleeping 5 hrs when I use to sleep 7-8. Next day headache pain in neck shoulder and tricep hand felt cold blurry vision. Blurry and double vision 1 week later both have subsided only get a lil when headaches come on. The problem I am having now is tension headache starting on left base of neck and going to front and around the head. They are brought on due to cracking neck from left to right. Do I may have had concussion also but whiplash may still be cause also. Pain in shoulder subsided but behind ears on both sides of neck are bothering me and looking down to quick and putting chin to chest.
