Thank you for writing to us.
Most likely with what you are describing you fainted and probably had what we call as a vasovagal syncope
This is not something serious and can happen in any person.
However having said that, as a general rule, any person who has fainted like this should be seen by a doctor.
The reason why I say that is because I would like to rule out other causes that may be serious like a heart problem, a problem with the brain or rhythm of the heart.
So, yes definitely you should be evaluated by your doctor and have routine tests like an EKG done to be sure that everything is okay.
In the meantime just relax. I am very hopeful that this is nothing serious and just one of those things that can happen from time to time.
