melody_sings,

Your post could have been written by many others on Neurotalk of the past decade. The way you describe things and analyze and project possible injuries shows you struggle with anxious thinking. 80% of people who complain about symptoms also struggle with anxiety and/or depression.

There is no value to looking for an injury, whether it be whiplash or concussion. Whiplash can be caused by 4 to 5 Gs of acceleration/deceleration. A concussion requires 80 to 90 Gs of acceleration/deceleration. That cannot happen unless one is strongly constrained with a seatbelt during a violent sudden stop or their head impacts an object.

There is an axiom that says : Treat the symptom, not the diagnosis. If your neck is sore, treat your neck. If you are anxious, try to resolve the anxiety, if you sense dizziness, treat the dizziness.

I suggest you get checked by a vestibular therapist. Vestibular therapy usually gets fast, even instantaneous improvements as the crystals in the inner ear get moved to their proper position. You can do some self-tests for vestibular dysfunction. YouTube shows them.

There are also some vision issues that can cause problems. It is more difficult to find a vision therapist plus they are expensive and rarely covered by a health care plan.

As a student, sleep can be a BIG contributor to these struggles. Quality of sleep, sleep posture, and more can impact these issues.

Simply dealing with student stress can be a problem, especially if one struggles with anxiety.
