<s>[INST] I hit my head yesterday.  I have a headache still; it gets worse with movement.  I'm also dizzy, off-balance when I walk, and feel nauseous when I move too quickly.  I haven't been to my doctor, but I am a nurse and I am scheduled to work tonight.  I am having some concentration difficulties and wondering if I should go to my doctor for an excuse for work, or if I should just push through and hope for the best. [/INST] Hi,Thank you for posting your query.I have noted your symptoms and these are suggestive of mild head injury and mild concussion.It may better to consult a doctor and get a brain CT (computerized tomography) scan done to exclude any internal bleeding in the brain, although the chances for that are low. If the brain scan is normal, you can go for work.For relief of symptoms, you can take medications such as ibuprofen or diclofenac tablets (for headache) and betahistine tablets (for relief of dizziness).The symptoms are usually self-limiting in nature and would resolve in a few days. I hope my reply has helped you.I would be pleased to answer, if you have any follow up queries or if you require any further information.     Best wishes,Dr Sudhir Kumar MD (Internal Medicine), DM (Neurology)Senior Consultant NeurologistApollo Hospitals, Hyderabad,For DIRECT QUERY to me:   My blog: </s>
