The doctor I was working with was over the phone and he didn't take insurance. He specialized in adrenal cases. I didn't notice changes taking pregnenolone. But back then I was having so many other issues other than low DHEA. I may get DHEA tested again sometime soon.
I've had pain in joints and popping too, but it comes and goes irregularly, staying away for months at a time. I figured it was just another of the many symptoms of adrenal burnout. :)
