hey Sandy, I too had fluid retention, but it did not start til a month after my last chemo, a "surprise" after-effect of the whole process, my legs felt like lead weights with skin very tight on my calves. None of the drs were too concerned, but living with it was too tough, so I asked for fluid tablets, which certainly did help reduce the tightness and lead weight feeling,
which allowed me to walk and relax more comfortably. I was carrying an extra 3kg or 3 litres of fuild and It takes time to reduce and I think its all about the imbalances of the body after all the chemo. I had a bunch of other "after" effects that did not show up during chemo, and Drs then advised it can be 3-6 month before everything settles down. I am at month 5 now post chemo, its only palpitations that are worrying, most of the other things have settled.
cheers B
