I hit the top of my head yesterday on a concrete wall. It was a mild impact but hurt. About 5 hours later i got very nausea and vommited about 4-5 times. After that i felt fine. Could the vommiting just have been from yogurt I ate 30 minutes prior to vommiting?.... The head is still sore today but no other major bad signs
If it was a single episode of vomiting & there is no bleeding from nose, mouth or ear, no convulsions & more importantly, no loss of consciousness after trauma even for a minute, then nothing much to worry. Just observation for if there is any further deterioration is sufficient. Examination once for eye signs, vitals, reflexes is advisable. If there is vomiting again, see your doctor soon. Hope this information is useful for you. Thanks. Regards.
