wait,B-12 deficiency can cause numbness in my extremities? and I thought it was the ascending aortic dissection that traveled all the way to the right iliac branch whereupon the false lumen completely blocked any indication of a pulse for a period of at least 8 hours (in the ER, while the attending followed the wrong path on his ddx). 11 hours of surgery followed. but seriously.. I'm sure it's the beta-blocker they have me on as a result (reducing contraction velocity). (and I've all but stopped drinking since the surgery.)
