and constipation can also lead to peritinitus, so be careful!
I have been having the same trouble with fluid at the moment ! It always used to be on my legs / ankles and i used it as guide to see if i was fluid overloaded. Now though its started to settle on my body (mainly trunk area) and it does make you feel very bloated . The main thing to watch for is getting very breathless , get hold of your nurse if you feel like that ! I was like that last year , my g.p. told me i had chest infection.I got so bad i could hardly breathe and was rushed to hospital , had a small heart attack .. and the cause .fluid had gathered around my heart, but like you my legs/arms looked normal.
