Everybody is ignoring me. Do I have to blockade the lab with my wheelchair to get some goddamn attention?

I have a medical conundrum of the first degree, guys. On Tuesday I was instructed by Dr. Singh, my shiny new cardiologist, to get to get my first Coumadin blood test TOMORROW — which is my last oppportunity before Sam goes out of town for eight days — BUT I CAN’T FIND ANYBODY TO DO IT! Dr. M’s office turned me down because they only do Coumadin testing on Tuesdays (what the fuck?) and the appointment desk at Dr. Singh’s office downtown at Baylor Hospital ISN’T RETURNING MY CALL.
