Always fainting....any advice?

I can not stand for more than five minutes without fainting....the doctor doesn't know what's wrong ( had many test done) does this happen to anybody else?

Thats being caused by decreased bloodflow to your brain, most likely due to collection of blood in your legs.
Do you feel dizzy immediately after you stand up after laying down/sitting for a while? Do your legs swell before you faint?
Ahh its so hard for a doctor to solve any problem without asking questions....
It sounds like you may be anemic or hypovolemic(dehydrated), its the most common cause of syncope.
More uncommon causes would be something like subclavian steal syndrome or a venous valve disorder. You should ask your doctor to perform a tilt table test, and full blood profile..you should definitely find the cause with both of those.

It does not happen to me, nor i think does it happen to anyone else! It is just not normal..

he check for anemia?

QUIT LOCKING YOUR KNEES!!
(joking, was always getting yelled at in basic)
FIND A NEW DOCTOR!!!
I'm not joking with that one! even if he's old family doctor and you've trusted him your whole life, whatever, that sound seriouse and you need to have more than one opinion anyways. I hope you find out what it is. sounds like poor circulation, but even so, is probably only part of it. I will keep an eye on this, and hope you find some help.

Are you eating enough? Do you take vitamins? Are you properly hydrated? You need a new doctor if yours can't find what's wrong.

This is not a normal occurrence and you need to go to another doctor to get some answers. Do not stand in one place for that length of time, do not lock your knees - this can cause fainting. Dramatically increase your water intake daily, make sure you eat regular meals and snacks. Do everything you can to prevent this from happening while you try to find the answer. Someone will find an answer. Make sure you are not dieting because this too can cause fainting. If you are on any medications, I would review the side effects of those also. If you exercise a lot, stop for a while until you have an answer to this problem - it may be causing dehydration which can make you faint. Find a neurologist and make an appointment.
