Thank you for posting your question here, I will try to answer it to the best of my abilities.
Sounds like you took quite the hit to the head, I am surprised no one sent you to a doctor right away to check for concussions. As it is, it is possible that you either have a concussion or retinal detachment
, it is also possible that it is nothing.
But in cases where there is a injury
to the head it is always better to make sure and have a check up done as soon as possible.
I hope this answered your question.
