Thank you for your quick reply! Just to clarify, a neurosurgeon is the one who would order the CT scan right, not my primary care doc?
Wow, I just looked up Tethered Spinal Cord and one of the symptoms is discoloration of the lower back. I have red striations on my lower back, right above my butt, and my dad has the same markings. His mother has the marks on the nape of her neck, I think. And Dad has always had back problems.
Dr. David S Bell also thought I had symptoms of EDS, because my fingers and wrists were hyper mobile, though they've stiffened up over the years.
