Alex, you have my total sympathy.
I contracted shingles just before Christmas, (around half of the torso in my case), and it laid me out for about two weeks. I'm still recovering - I still have a tingling sensation around the waist, which only stops when it is replaced by a sensation of pressure (like being hugged too hard), and my general fitness / endurance is still way down on where it usually sits. I reckon I've got another 2 - 3 week before I'm fully back to my usual self.
