Less crippled than last year

Hardly crippled at all, except under some circumstances.

I keep off the dairy and my back continues to improve. I have managed to do the following things recently which I couldn't do a year ago:
* stand during an entire gig then get the train home afterwards
* travel by plane without assistance occasionally
* do two ceilidh dances in a row
* go to a nightclub, stand and dance lots, then get the train home afterwards

I still cannot
* stand on a train without having great pain and difficulty walking for several hours afterwards
* travel by plane without assistance on all journeys

I think that's it...
