My husband was dx'd in 2/2007. He was exhausted, shaky, needed a cane to walk up the stairs, in a wheel chair for short distances (down the block). The deficits started lifting approximately 5 months after radiation. Now he can walk just fine, is not as tired, and no longer is shaky. The radiation effects stay in your body for 6 to 12 months. You really won't know what the leftover deficits are until that time has expired. Good luck.
