Hi there ~
If your CT is normal you do not have any cause for concern. However, it is possible that you have residual symptoms from concussive injury
. I think you should visit with a doctor who could be a primary care
physician nor necessarily a neuropsychiatrist and first have yourself get a general check up and take medications. Analgesics help with the pain. However, if despite being on over the counter analgesics your pain is not better, you will need to visit with a psychiatrist.
I hope this helps. Take care and have a lovely day !
