my daughter fell and bumped the back of her head.   She cried for abput 5minutes and then was fine.  She went to sleep 6 hours later and after 3 hours of sleeping woke up crying and said her head hurt.  Should she be seen by a doctor?  She keeps crying and waking up from discomfort.
If your daughter had no episodes of vomiting, unconsciousness, convulsions, sensory or motor problems, altered behavior etc. then you need not worry. After 4 to 6 hours of head injury absence of above-mentioned complaints usually rules out possibility of serious brain injury or brain bleed. For headache, you may give paracetamol or ibuprofen. If pain is not relieved after medications then you will have to consult doctor. For further queries regarding this disease or its medications you may take my appointment at Chat Doctor.
