I hit my head hard and was unconscious for ten minutes, should i talk to a doctor?

The Dr. can examine: After a head bonk, a person usually goes to the ER or sees her own doctor if she: vomits more than once, loses consciousness more than 30 seconds, has a headache getting worse over time, has changes in her behavior such as getting irritable, has changes in coordination such as clumsiness, is confused such as difficulty recognizing people or places, or has changes in speech.
