[|Human|] Hi there:) I hit the back of my head almost 3 months ago because of a wooden beam I did not see. I have been on Prednisone for a week treatment . I recently went to the doctor and she saw that there was still a bit of inflammation in the back of my head(she believes I suffered a concussion). I am getting pain on the left side of my head that radiates down my neck, to my shoulder and down the rest of the arm. Why is this ? :( I do not have much money so I have not done any scan of whatsoever:/.
[|AI|]  Hi welcome to Chat Doctor. In case persistent pain at the back of the head following head injury, it's extremely important to suspect brain contusion. This can result in seepage of blood into the nearby tissues causing irritation of the meninges and leading to set up of inflammation. This can cause persistent neck pain. It's extremely important to have a non contrast CT scan abdomen to rule out meningitis and signs of raised intracranial pressure. Following which a CSF lumbar puncture can be done to start an empirical antibiotic therapy to treat associated meningitis if any. Therapy can last for 21 days. Consult your neurosurgeon for further help. Thank you.
