Hi, I'm 25 and for years I've been having problems with blacking out, dizzness, or fainting. Along with my black outs my tongue goes numb my fingers are tingling then a sharp pain on the side of my head comes and shoots to the back of my head. I've always had low blood pressure so I thought that was the cause but now it seems to get more frequent and worse. Two months ago I blackedout in my bathroom and started shaking uncontrollably and my tongue was numb fingers tingling and the sharp pain in my head. But a few months before that I had the same incident and my brother was terrified and asked if I was ok I just laughed it off cause it was a shock. Those were the only times I uncontrollably shaked while blacking out. Now I black out very frequently a few times a month. My other symptoms is I'm constantly tired and no energy or feel weak. I have to constantly urinate right after i have and I went to the doctors had blood and urine test and no infection. So no utility or bladder infection. Now for about a week in a half I feel like the rooms spinning when I'm laying down or stand up. And it comes and goes. I just need to know if anyone has this problem and is it just low blood pressure?
