lingering side effects after finishing herceptin

[murphy]

I finished my year of Herceptin a month ago (after x12 Taxol and x32 radiation). I'm not taking any estrogen inhibitor. I've been experiencing leg muscle pain which increased along with my last few Herceptin infusions. I've been trying to find out if the pains are in fact connected to Herceptin. The drug company is no help—though "muscle pain" is listed as a possible side effect. And my oncologist doesn't know anything about it and just says any side effects should resolve in a few months. Does anyone have any experience with Herceptin and muscle pain?
