While opening the door to my garage (heavy metal door), there was a shoe behind the door preventing it to open all the way, which I did not know, so ran into the side of the door. The door hit my left side near the temple. Immediately after I was in extreme pain and felt a little disoriented and nauseas. All day I have had a sharp, throbbing pain in my temple that travels down my cheekbone and into my ear. The pain is not constant, but occurs often to be concerning, and at least for a minute. Is the pain due to trauma to the artery running through my temple and do I need to go to the hospital? I have two small kids and try not to overact by running to the doctor with every bump. Thank you for your advice.
