4 weeks ago my daughter 10 had a concussion. was admitted and had ct scan. came back clean. now struggling with vision problems, left eye turning inwards and vomiting if pain is to much. is this related to concussion?

Worrisome : I can't link this to the concussion but cannot exclude it either. For the eye to turn in suggests pressure on the nerves controlling eye movement which is definitely a reason you should go the hospital immediately & have her seen.

Must re evaluate: There may be swelling and impingement on the optic nerve tracts and cranial nerves. Please see the Emergency department at the same hospital right away.
