The guy above me is right.
Maybe when you were younger, the cardiologists were right and an irregularity in the heart didn't matter much. Obviously it does now. Go to another one. Your low blood pressure would be fixed by sodium but damage you more than it would help under this theory.
The emergency room is a bit of fearmongering; just go back to Cardiology.
Do not increase the amount of sodium in your diet without consulting your physician.
Low blood pressure. Increase the amount of sodium in your diet.
If you smoke stop smoking. If you dont breath properly (you workout so i hope you do), start. Do not make sudden movements especially if you've been still for a while. I have blacked outc several times due to dehydration, lack of oxygen to my brain (holding smoke in to long)(not breathing properly). I went to emergency room the doctor told me nothing was wrong as well. I hope the solutions i provided are right. I also have this reappearing "rash like" thing on my back. My doctor recommended some creams but nothing prevented them from eventually reappearing. Sometimes I even get wierd needle like scratches in random place when im sleep so.... Weird things happen and sometimes we just dont know why.
You require an evaluation at an emergency room.
I can make a good guess at what is wrong with you but I am not going to do that. You clearly have postural hypotension, and the solution is probably simple (but it might not be).
If you continue with the absurd irrational decision not to see professional medical help you have a significant probability of ending up dead. You know. With arterial embalming fluid in your veins and everybody in the family that wears your size clothing divying up your good clothes and jewelry.
Any loss of consciousness requires an immediate in-person professional evaluation by an M.D.
you may be having tia a form of stroke. get it checked please
You may have a more serious issue. If your blood flow isn't where it should be you may be having issues with blood pressure. That can cause black outs, tingling limbs and chest pain. I would go to the doc and tell them what is happening to you.
