I know what you're going through. I had this similar experience with my neck and head. The dizziness you felt at first I did. From my experience, I believe you should invest in taking care of yourself and always act smart. If you know what makes you feel overwhelmed, I suggest you back out and don't mind what people say. Do not allow people to override that conviction you have when something's not right. Once you are free of symptoms, start exercising, slowly at first. Do some jogging everyday for as often as you can. Once you start this you'll start coming back. I must confess there will be times when you feel that life isn't worth it.But please keep going at least for me. ;-). Listen to relaxing music, during times like this. It'll help you get over this faster. It did for me. After you do this for more than 5 months, you'll feel a rush of recovery , people are different so time can vary. Keep going , your brain will adapt slowly, but it WILL. Take care of yourself. I still have a few issues, but I'm very near my old self. 1yr after injury.
