Thank You for contacting HCM. Pain after head injury can be simple concussion or could lead to sever bleed. It takes around few days to recover fully. I would suggest following: Take rest. Avoid sternous activity. For headache acetaminophen can be taken. Take a cloth piece and heat over flame so that it becomes warm, then place it over the eye. It will give soothing effect. Black eye is due to blood accumulation under skin. Avoid drink till she becomes healthy. Take healthy food including fruits & vegetables Report to hospital (preferably to neurosurgeon as he is specialized in head trauma cases) if: Condition remain same after 4-5 days Any unusual symptom appears Condition deteriorates. You loose conscious or has altered state & talk irrelevant things. There is visual problem. Hope this answers your question. If you have additional questions or follow up questions then please do not hesitate in writing to us. Wishing you good health.
