Well, I certainly don't remember linking to anything like that, but I am on a lot of drugs. So, I went back through all of my posts for the last month and sure enough, I have to apologize to Hanan over at Grow a Brain. Even though I link to him a lot, I never noticed the Moving to New Zealand site he put up. It is really fascinating to watch someone's dream while it is happening.
I have found it helpful to do the stretching exercises my physical therapist recommends. Do some core strengthening exercises, such as the ones highlighted at The Mayo Clinic. By keeping your core strong, your back won't put itself in a position to cause that sciatica pain you are having.
