thanks traveller - i'm following up with my friend who offered to lend me the elbow ones it sounds like they're better.

well I tried swimming today... and managed to sprain my toe! Of all the stupid things to do huh! I was pushing off the wall and it caught or slipped on something somehow and YOUCH! So now I have a big fat red swollen bruised toe! The actual swimming and gentle water-walking went well and didn't cause pain. As for the sprained toe (i'm assuming it's not broken - shall check with my physio on thurs), well it doesn't really make too much difference given I'm not walking much anyway! But still, I can't quite believe it
