What Causes Crossed Eyes After A Concussion?
Your anxiety could have had a greater impact than the concussion itself
Detailed Answer:
Thanks for asking on HealthcareMagic.
I have gone carefully through your query and understand your concerns. It seems that the concussion temporarily affected the capacity to control the eye musccles and focus the eyes together. This is likely to have made you cross eyed for a couple of weeks. Such a thing can happen and I have heard of such a thing happening. However, with the subsidence of the concussion the problem should subside as it happened in your case.
I doubt if this would have a long term effect on your personality. However, your apprehension could indeed have affected your personality.
Let me know if I could help further.
