the biopsy went very well but we were surprised it was done with just a local (no sedation) and in the vascular clinic (not the hospital). We are still in Sacramento because my son's leg hurt too much to fly. It hurts to bend it (because he has to use the muscle they cut into). The docs were super pleased with the sample but it will still take a few weeks to get definitive answers. I have to say, the neuro's here have been kind, caring, communicative, patient and accommodating. I feel like I've been transported to a different planet and very fortunate to have been able to get in here, and so quickly.
