Photosensitivity is a common symptom of concussions. For some, it reduces over time. For others, it may reduce some but still be a life-long struggle.

I have worn sunglasses or photochromic glasses since 1970 after a concussion.

Strobing lights can be miserable. Add the sounds and you brain can easily become overwhelmed. Over-stimulation is often the most prolonged symptom of a concussion.

You need to stay away from these events for an extended period then slowly try increasing your stimulation level.

Vision contributes greatly to balance. When your vision is struggling due to lights, your brain cannot use your vision to help with your balance.

Your brain can also become overwhelmed with stimulation and cause your vestibular system to become overwhelmed.

It is unfortunate you had to experience this. For many, doctors explain this issue and tell the patient to avoid excessive lights and sounds until after all symptoms are resolved. Even then, returning to these activities is done slowly.
