Thank you for the query.
Yes, you should see your doctor. As brain is completely hidden under the skull you can not be sure what is happening inside without head CT. Especially after the trauma. Of course there is plenty of neurological tests and symptoms but neither of them does not give 100% certainty that there is no internal bleeding
. Vision problem can be the only symptom of such bleeding.
Sore neck is typical for such traumas, however in some cases during the CT some fractures
of this part are reveled.
That is why I suggest you to do not wait anymore and visit your doctor. Waiting is too risky.
Hope this will help.
