Hooray for return of jane's water 
topsy - I second what Cakes said about the sore arm. its the veins. You might find you get dark tram lines up the back of your wrist where they put the chemo in (Its a good look obviously, but it doesn't last
) also my arm went a bit sort of lumpy looking esp. in the fleshy part.
I was advised to rub ibuprofen gel into the arm to help the pain. But yes definitely mention it because you can get inflammation in the veins (phlebitis???) which they'd want to know about.
Have a lovely lunch with your friends 
cakes - I think the main cause of my problem is over use,so a RSI - not sure what I've been doing, - don't think its typing because its my left hand, I thought I might have done something to it at yoga. Basically despite the fancy name, its pretty common and is of the same family as tennis elbow/ golfer elbow etc.
Good that the thuglet is keeping her distance, - hope she doesn't cause problems by chumming up with Miss Rude.
Stars, I just saw your other thread about thermometers, I got myself an old fashioned mercury one, - because my digital one started getting ridiculously inaccurate. But you might have to scout around a bit to get one, - I was told recently that they aren't stocking them any more. - It may be different where you live though 
Smee - I bet DS loves the builders if they are teaching him to climb scaffolding 
Broke here as well, - and we got a whole lot of expensive things coming up, (not hugely expensive but just a bit extra on the monthly budget), I'm also trying to save for a yoga retreat in Spain next year which my teacher is running, - it sounds great, but is quite costly.
