Well that was a series of odd sensations. 0.o Specifically, the "lower extremity intravenous ultrasound," which basically consisted of having a very cold, blue-schmear-covered sensor poked anywhere on my leg where the artery was near the surface.
So, the doc will have those results in a few days, and I have a followup appointment for two weeks from tomorrow to get the diagnosis, unless I hear otherwise earlier. (Always two weeks. Oy. My leg hurts, ya bums!)
