Right foot very swollen--Herceptin?

Hi All,

Some advice. I just finished my last herceptin ten days ago. From the beginning, my feet/ankles would swell afterwards. After the last infusion, my right foot is swollen (very) most of the time, even when I wake in the morning, although it's somewhat better in morning than at night. The left is also swollen, but as before. Has this happened to anyone on the board. My last echo, about a month ago was good--LVEF was still 60%.
Thanks.
