Hi Bugby, Most of us start with a tilt table test, and cardiologists will usually rule out structural heart problems first. If blood is pooling in your legs, surgical stockings can help (although they never help me, honestly) and if blood is pooling in your abdomen, an abdominal binder can help (that did help me). Although “band-aids”, these can help while you and your doctors are trying to locate the cause. Do you have a copy of The Driscoll Theory? That may also help you at this early stage. (((hug)))
