Dear Paul,
Gemzar can cause swelling in arms and legs. Some patients describe it as a heaviness. This will go away when the Gemzar treatments are finished.
Diuretics upset the electrolyte balance in our bodies so the oncologist was being cautious in recommending the minimum. Sometimes by making a side effect just a little less annoying allows us to carry on with the chemo.
Your kindness and willingness to find answers for your wife is commendable and goes a long to ease the burden of the treatments.
I hope she is feeling more comfortable.
Connie
