I'll be interested to hear how you get on with the leggings, I know what you mean about the swelling too, I swear I could feel it moving in the water when I tried to walk forwards.
A warm endless swim spa is my dream....

oh well...
Here in the UK the darned weather is constantly changing, and mostly seems to like being damp and chilly - the CRPS definitely doesn't like it, and given the funds I would move somewhere warmer with a more stable temperature straight away! I hate feeling so cold and miserable all through the cold months, with our recent heatwave I've realised how much happier my leg is when it's warmer - bit of a shock how much difference it made. Nice at the time, but it makes you come back down to earth with a bump when it goes colder again.
Good luck with it all, that positive attitude of yours is a great weapon in the fight!
Bram.
