Hit upper left arm right above elbow, felt out of focus, passed out. Why ?

My upper left arm right above my elbow got hit by a refrigerator case door at the food market last night. He hurt real bad and then I got sick to my stomach and felt like I was going to pass out. Everything was out of focus and a few minutes later I turned white and passed out. Can this happen from just hitting a bone real hard?

Normally when there is severe unbearable pain the autonomic nervous system (ANS) dominates over the body and stimulates vagus. this vagus causes sudden reduction in the blood pressure and supply to the brain leading to syncope (fainting) what is called as vasovagal syncope.
Sick stomach can cause loose stools and vomiting which can cause loss of body fluid leading to dehydration.
In your scenario-
it could just dehydration/vasovagal syncope alone or can be caused by both.
Things to do-
1) drink plenty of water.
2)immobilize the injured limb and visit an orthopeadician to rule out a fracture.
3)Take antacid ( tab pantoprazole 40mg once a day in empty stomach )
4)take adequate pain killer ( tab. paracetamol 500mg twice/thrice a day ) avoid NSAIDS( diclofenac, aceclofenac ) and tramadol for pain as both can worsen the condition of the sick stomach.
5) apply cold compression over the injured region.
6) subsequent episode of fainting occurs to visit the hospital for further management.
7) topical pain killers any gel,ointment, spray can be applied.
