1st question is blood psi before & after you stand? Blockage? Bad valvae? Eating enough? Ear issues? I reduced fish oil from 3000mg to 1000mg cause I was getting a bit dizzy.

When I got my spinal cord injury & lay flat for 3 months, they had to little by little raise my upper body with wedges. 3 months after that in rehab hosp they strapped me to tilt table for 1/2 hr/day. Heart had to get use to pumping again.
