Hi Sirs,
In 1990, I had spondylitis and was put on Prednezone for a few months. following that, I stood up and nearly blacked out. Since then 90% of the time I stand up, I have a sensation of blacking out. The patterns change a bit over the years, left arm/hand cramps, or both arms feel heavy, pounding in my chest, usually on the left hand side, pounding/sound of blood rushing in my neck both sides, pounding in my temple, or a crampy feeling in my temple/head. MRI and CT scans are normal.
Help please, it is very debilitating. My name is Cutie
