Ballooning Knees - Arimidex? Herceptin?

[Donna]

Hi Amazing Group,

I finally finished my AC and T and started herceptin - had my rads - have been taking arimidex for 2 weeks now. My knees felt "bloated" on the taxol and herceptin together. Now my knees are swelling out like balloons and I can't bend them very far. It doesn't hurt unless I make a side step and then it hurts alot.

I am so disappointed to have this - I finally got my husband to take ballroom dancing with me and this is really making it hard for me to enjoy!!!!!!!

I have to think this is the herceptin, the arimidex or a combination - any ideas? Anyone else dealt with this? How about Femara? Any input will be greatly appreciated.

Thanks so much and have a great weekend!
