Hi there ~
It is always good to have a complete scan of your head CT to make sure there is nothing going on in your brain. You may have had a concussive episode which will get better over time. Pain killers are helpful to help relieve both the pain and anxiety
surrounding what may have happened to you. I hope you consult a radiologist
to get the CT scan
done and have it checked out by a psychiatrist
who can guide you further.
I hope this helps. Take care and have a nice day !
