When will I have radiation treatment?

My last embolization was November 12, 2012. I am supposed to have radiation treatment. However, originally I was supposed to go for labs in February 8 and then back that Monday on the 11th. I don't understand exactly what the proper procedure is. I was told that everything would be done in one day. Not two visits. We live 3 hours away from the Mayo in Jacksonville. They are trying to get everyone where they can be there at one time. But my question is, how long before the vessels start to enlarge again? I am ready to get this thing taken care of.

Asking again. How long should I expect to wait until I have radition treatment? My procedure has been scheduled for February 11, 2013. I am worried that my AVM may be enlarging since the last time I had it looked at was December 7th of 2012. I have already had 2 embolizations that decreased the size by 50%. I have started having vivid dreams again, dizzy spells, and headaches. Feeling really tired too. Anyone got any thoughts?
